@Kylor:
I'm breakin' my vow of silence here. Let's see if I can make it worth it.
People interpret characters and value them based on different things. Maybe I can get that. You seem to be gauging characters based on the coolness of their accomplishments. I could be wrong, and feel free to correct if I am, but that's how it seems to be. But sure, let's go with that.
As was mentioned, Chopper saved Nami's life at Drum. And every battle or situation since, he was the one who tended to everyone's war wounds, and made sure they were well enough to continue fighting well afterwards. You need to pull off a quick blood transfusion after some idiot nearly dies because he can't keep it in his pants? Chopper's the guy to do it. Who was able to figure out that the kids at Punk Hazard were being drugged by a substance that was actively killing them, and then spent nearly all of the arc afterwards being one of the only guys consistently focusing on keeping the kids alive and safe? Yeah, it was the little reindeer guy. But doctor stuff wasn't the only thing he was good for either. He stuck with Usopp and helped him to victory in Alabasta, even though they were up against trained assassins who, by pure numbers, had a huge advantage. He's the one who fought tooth and nail, nearly to the death, at both Sky Island and Enies Lobby, even though he was scared to death and getting the crap kicked out of him all the way. Because he's not some run-of-the-mill shonen ubermensch like Sanji is. It's easy to charge into fights, look cool, and perform amazing feats when you're a brute character with a joke attached to him, who can do impossible things with the same amount of effort that most people put into breathing. After a point, that just stops being interesting. Chopper might be tougher than your average reindeer, but still he routinely winds up against guys who by all means could roast him alive. But he sticks it through, even though he's not quite as strong, even though he's afraid, even though he's still more or less a child who's still experiencing the world for the first time, and even though he's constantly being belittled and underestimated by nearly everyone he meets because he's a reindeer and a monster. He sticks it out, he fights anyway, and he does the things only he can, because he's a man and a pirate, and that's just what pirates do.
And here's one thing that Chopper never did. He never left his friend to die because of some archaic concept of chivalry. Just because Chopper looks good as a plushy doesn't mean he can't be cool sometimes too.
This was well argued. But I take a little issue with the bolded part. Maybe cast your mind back to Skypiea, eh? Sanji's frequent 'doing cool things' isn't just down to the fact that he's superhumanly powerful. His saving of Nami and then Usopp from Maxim despite the fact that he'd already been fried by Enel (ie knew what he was up against and that he couldn't win) and that is a lot more appreciable than what you're implying we get all the time.
(Incidentally, keeping to Skypiea, while Chopper's overcomign of his fear was pretty cool, that actual fight against Gedatsu was disappointing, since Gedatsu seemed to be built up to be pretty dangerous, but half lost due to his own stupidity . . . )
Anyway, it does seem that posts are getting pretty heavily shifted toward bashing the other character. Maybe a little calm is in order ahaha.
Surprised to see Sanji pulling away, campaigns considered. It's ncie though; I hope he wins and that he gets a little redemption in Dressrosa in time to help out in future rounds.
