True, however the real question is what he could have done with enough time. Oars was immune against small amounts of pure salt - that is why I doubt mere seawater is enough to disable the "next level" zombies.

I too believe that every other Shichibukai would royally kick his butt in a one-on-one fight, even Crocodile. But one can't deny that the Kage Kage no Mi has its unique advantages. It is also uncertain how many people know about this special weakness - and if the other Shichibukai have similar weak spots.

- Crocodile's power can be negated with any liquid substance

-Kuma is a monster, but he lost his free will. A sword is only as strong as the one who wields it. A braindead cyborg is just a predictable machine. Noticed the fight against Ivankov? He got kicked around like a football...the former Kuma would never let his guard down like that (but repel the attacks).

- Hancock, while strong, the moment someone disables her devil fruit she suddenly becomes a lot less of a threat. Momongo demonstrated that by stabbing his hand. Ok, she can still partially petrify her opponents by kicking them, but compared to the other Shichibukai it is nothing.

For the rest, not much is known so I can't really rank them... however the above 3 I would consider the weakling trio of the Shichibukai.
