In my opinion, the Yomi Yomi no Mi is the best Devil Fruit out of these four, because eating it will grant you a second life. Along with some soul based powers, and Brook was shown to reattach his after being decapitated, overall, the fruit is very useful.

Of these, I’d say gomu. Overall I’d say gasu, it’s way too versatile to not be #1

If I had the revive Revive fruit, I did at least try and pull a Blackbeard

Then become stuck in your soul form cause if you go back you die

Luffy's fruit is good, but good lord its overrated AF!

Either way, could be a soul infused with a z oan so it could take the form of something cool like a dragon or human

Now that what we know what the Gomu Gomu no Mi actually is, it’s objectively the best Devil Fruit on this list
