Best Fruits IRL

 * Pika Pika no Mi: Logia invincibility, lightspeed teleportation, lightspeed attacks, and lethal lasers that can pierce or slash almost anything. This fruit excels offensively, defensively, and you can't go faster than light speed. The large population of high-tier Haki-users is really the only reason why this fruit isn't OP.
 * Shiku Shiku no Mi: While we don't know the full potential of this fruit yet, pandemics can devastate entire populations even in the modern day. If you want to disable or kill entire armies, this fruit would be a great WoMD. It's no surprise that a sadistic villain owns this fruit, because it's one of the few fruits that I would not want to actually use simply because of how unethical it is...
 * Nomi Nomi no Mi, Baku Baku no Mi, & Raki Raki no Mi: These fruits appear to be the most profitable.
 * Nomi Nomi no Mi allows you to create inventions that would guarantee a huge profit. Having servants is also a plus. I would look weird, but I might invent something to bypass that.
 * Wapol proved that the Baku Baku no Mi can produce perfect toys that could make you a billionaire and king within 2 years! The constant hunger is going to be the biggest issue.
 * Having extreme luck would make gambling consistently profitable. The only issue is that this kind of luck is not absolute, meaning I would still need to be careful.

Best Fruits in the One Piece World

 * Goro Goro no Mi: extremely destructive, has enough voltage to consistently knock out anyone not made of rubber, allows lightning-fast teleportation, enhances Haki (which also allows Enel to attack from long distances), has Logia invincibility, and can prolong the user's life by defibrillating their own heart. Luffy having a rubber Devil Fruit was the primary reason why Enel lost against him, and their duels were still close.
 * Hie Hie no Mi: a Devil Fruit that effectively negates drowning (by freezing the water before you land into it) is already important in a world where sea travel is the norm. Being able to make even a Diamond-Man like Jozu both immobilized and frail is quite a feat. I could also produce ice-barriers for extra layers of defense if my Logia invincibility is bypassed. The ice-weapons created by this fruit are also implied to be sturdy and deadly.
 * Doku Doku no Mi & Gasu Gasu no Mi: poison and suffocation managed to defeat Luffy initially, and Blackbeard's entire crew got 1-hit KO'd. Magellan is one of the few characters that Luffy failed to defeat because Venom Demon: Jigoku no Shinpan (which can infect inanimate objects!) has poison so lethal that even someone who gained poison resistance (like Luffy) was implied to be unable to survive this poison.
 * Ori Ori no Mi, Noro Noro no Mi, & Hobi Hobi no Mi: the ability to stun your opponent is a cheap yet effective way of winning a duel, especially if you combo it with a legendary weapon or Seastone weapons. Unsportsmanlike, but something a pirate would do. Honestly, if these characters managed to master Soru or didn't have to worry about Haki then they would score a quick instant-ko against almost any opponent.
 * Noro Noro is the best for being a projectile weapon that most opponents would not be expecting initially. Foxy has also shown variations of the standard Noro Noro Beam that are harder to dodge. If Foxy didn't rely on using primarily blunt force against a rubber-man like Luffy, he would have won their duel.
 * Ori Ori is able to function in close combat or mid-range, but will struggle against agile opponents.
 * Hobi Hobi is actually the worst for having no combat abilities beyond touching your opponent, meaning that you are defenseless from enemy counterattacks. Toy-slaves are not guaranteed to be powerful enough to defeat your opponent, assuming that they are even nearby to assist. Sugar sometimes relied on pretending to be a normal girl to ambush her opponents.
 * Kage Kage no Mi: having an invincible bodyguard that can swap places with you, impale a giant-giant, indefinitely harass your opponent as a swarm of bats, and trap your opponent in a box already has a lot of potential in combat. Being able to knock out opponents by stealing their shadow, and then have that opponent vaporize in the sun is OP if you can pull it off. Moria also confirmed that there are many strategic benefits for this fruit as you could potentially stockpile a zombie horde or create a zombie that is potentially physically stronger than the owner of that zombie's shadow. Jinbei, Kaido, and Luffy confirmed that Moria lacked the skill or abilities to fight effectively whenever this Devil Fruit failed to maintain its gimmicks, but if Moria did have the natural physique of these opponents then he would be far more threatening. Imagine fighting Kaido alongside an invincible Kaido-shadow that intercepted your attacks; you would struggle to win that war of attrition no matter who you are.
 * Riki Riki no Mi: in a world where raw power is a major key to success, having a Devil Fruit that is simply raw power with no gimmicks is potentially the most important fruit out there. It seems to multiply a user's natural strength, meaning that someone like Garp would be several times more absurd than he already is.
 * Magu Magu no Mi: being able to easily maim One Piece's most powerful pirate alive at the time and consistently maim other heavyweights is astonishing. I personally would not enjoy this fruit because it is simply too dangerous, which is actually fitting for someone like Sakazuki/Akainu (violent, hyperaggressive, reckless).

Best Devilfruit Users

 * Kuma: Pacifista durability that can be upgraded if necessary, mouth cannon can surprise opponents, Nikyu Nikyu no Mi is also a great Devil Fruit by itself: it can dodge or deflect most attacks, is powerful enough to pierce through opponents with extreme durability like Franky, allows lightspeed teleportation, and can banish opponents by sending them flying for days.
 * Marshall D. Teach: Managed to have two of the most powerful Devil Fruits, has the skill to maim Shanks before getting his Yami Yami no Mi (which is quite a feat), has physical strength rivaling that of other heavyweights like Garp, and has the sturdiness to resist the increased pain weakness of his Yami Yami no Mi. We might see Blackbeard steal other fruits in the future as well...
 * Luffy & Sengoku: having a god-fruit be used by a character who is already physically a heavyweight guarantees that these guys are going to surpass other Devil Fruit users in raw power. It's unclear at this point how extreme these Devil Fruits are due to their lack of depictions, but a god-fruit is still the power of a god. Luffy dominating Kaido (who has the dragon-fruit) and Sengoku stalemating against Blackbeard are incredible feats of power.
 * Van Augur: Being able to both snipe from over the horizon and then use Wapu Wapu no Mi to dodge attacks or reposition yourself after you get spotted will make Van Augur mostly untouchable since he can maintain a permanent range advantage against almost any opponent. Usopp's new Haki abilities aren't guaranteed to work since Van Augur would still have a mobility advantage and Usopp's projectiles might be slow enough to react to and dodge.

Meh Or Bad Devil Fruits (but I still like them)

 * Moku Moku no Mi: I like the idea of combining flight, midrange, and smokescreens to disorientate opponents. In One Piece, it's arguably the weakest Logia and smokescreens do nothing against the best Haki users. Even IRL, being negated by fire (so, anyone with a flamethrower) is kind of pathetic. Gasu Gasu no Mi is arguably able to do anything this fruit does, but better.
 * Shiro Shiro no Mi: being a literal castle that can still walk/drive while having the option to be human-sized sounds awesome on paper. The only issue is that its raw power is unremarkable, especially in the One Piece world.
 * Tori Tori no Mi, Model: Phoenix: flight combined with nigh immortality sounds so great. However, IRL, it doesn't do much compared to some logias.
 * Tori Tori no Mi, Model: Falcon: falcons are the fastest bird, so this should give you unmatched air-speed. Faster fruits exist, other forms of flight exist, and Phoenix is objectively better overall. The reason why this still warrants a mention is that flight is awesome, and flying fast is better.
 * Bane Bane no Mi: some fruits like Pika Pika no Mi are objectively faster, but bouncing like a pinball sounds so much fun.
 * Mogu Mogu no Mi and Oshi Oshi no Mi: Merry Christmas managed to use this fruit to its fullest potential by showing how effective it is to use digging to outmaneuver opponents. Making tunnels might also be fun.
 * Horo Horo no Mi: The "hide and be a ghost" tactic was genuinely effective and could have worn down any opponent if Usopp wasn't so smart and... "already negative".
 * Yomi Yomi no Mi & Jewelry Bonney Fruit: Eternal life is neat.
 * Bari Bari no Mi: While this fruit lacks offense or agility, Bartolomeo managed to make it work so well against post-timeskip combatants despite him lacking many skills without it. This fruit is surprisingly useful and trollish.

Devil Fruit Combos
Assuming Blackbeard isn't the only person who can have 2 fruits at a time, what would be the best combos based primarily on their synergy?
 * Yuki Yuki no Mi & Hie Hie no Mi: A blizzard could slow down your opponent while assisting your Ice Age. You would bury your opponent.
 * Suke Suke no Mi & Nagi Nagi no Mi: Sanji didn't need Haki to fight Absalom because invisibility can still be detected. You would need to negate other senses to be truly unavoidable. Being both mute and quiet would make you the ultimate TF2 Spy.
 * Shiro Shiro no Mi & Deka Deka no Mi: Both of these fruits make you gigantic compared to your opponent, but the former allows you to manipulate space around you so that you can still do normal tasks like walking down the street or entering a building without being too big. Being a city-sized castle would give you massive cannons and dense walls.
 * Riki Riki no Mi & Deka Deka no Mi: Raw power combined with being the size of a mountain should make the most powerful thing ever. The only issue would be being too destructive.
 * Magu Magu no Mi & Atsu Atsu no Mi: This sounds like overkill, but I would assume that your already destructive lava could be more powerful if you could increase the heat it outputted.
 * Wapu Wapu no Mi & Mato Mato no Mi: If you can guarantee a hit no matter where you are and are able to teleport away, then you can snipe your opponent from long range while falling back if your opponent attempts to approach.
 * Doku Doku no Mi & Mato Mato no Mi: The deadliest fruit combined with the most precise fruit.
 * Kage Kage no Mi & Yami Yami no Mi: I don't know how exactly this would work, but having shadows and darkness combined sounds like it has potential for some evil power.
 * Bari Bari no Mi & Kage Kage no Mi: You'll have one layer of indestructible defense combined with a bodyguard that can operate on its own and swap places with you. Even for those Haki users and those with anti-Devil Fruit weapons, this is one defense that would be difficult to break through.
