I'm wondering why people think that Luffy Zoro and Sanji are the best? I'm not saying you're wrong, but what makes them so much better than Franky and maybe even Brooke. I also think Chopper has become a looser now. Also Ussop has potential, IMO and deserves more credit.
Franky was able to fight against Luffy in water 7 (though luffy had no gears). Is it just because he's a noob with a lower bounty? Because robin has a higher bounty than Sanji. Clearly he's physically strong, he was able to tear the 2 pillars in TB easily. Not to mention the crowbar to the head didn't even affect him. A karate chop from Nami hurts the other 3 (though that's more of a joke).
Brook has some pretty sweet abilities as well (though I think he states Zoro is on a whole different level). He sliced Taleran no problem which was pretty amazing considering the strength of the zombie generals, Luffy couldn't even phase them, IIRC. He was able to put the fish riders to sleep. He had a combo with Zoro (though that doesn't mean much). He can take dumps!
Am I the only one who thinks Chopper has gotten so much worse since he first appeared? Back on drum he was a monster, he took on Chess and Kuromarimo. Now every time he even takes the weakest guy it's something amazing, except Cp9, their really was no weakest (except Spandam). It's also assuming that hogback and the priest he fought were the weakest. Hogback really wasn't even a fighter, just a doctor and the priest didn't even get respect from the other priests. Mr. 4, Lasso and Christmas was his peak I'd say. Honestly, on fishman island he needs to tool on someone.
Ussop's a pretty strong fighter, when he wants to be, his downfall is he never wants to be. I won't use Perona, because he was pretty much beating on a little girl since her powers couldn't hurt him. He took a pretty bad beating from Mr. 4, Lasso and Christmas I mean he withstood so much damage. He fought pretty well against Luffy and took quite a betting (though getting owned doesn't make you good at fighting, Luffy can own me also). He defeated Chuu and wasn't really even hurt. He took out Jango who was supposed to be stronger then Sham and Bucchi (though they were hypnotized to be super strong). He did some awesome sniping on the gates of justice and is just an amazing sniper, he's not up their with some of the others but he's still pretty good.
