This probably makes how many threads? However the first thing I noticed in this thread from the poster, was that the title and the poll description is biased. It's self explanatory.
Either way, I choose Sora, the original. I don't think there's anythign impressive about Roxas duel wielding. The simple thing is that Sora's style is one keyblade, while Roxas likes to fight with 2, it's what separates them. Funny, Roxas is Sora's double and he wields double the keyblade.....anyway, Sora can duel wield, and very skillfully too from what I've seen in the Sora/Riku vs. Xenmas fight. He just doesn't use it.
Other than this, I've seen everything that kid went through, for three freakin' games. I like his attitude. Happy-go-lucky but still serious when need be, fun but sometimes gets upset, angry, and impatient. When someone is all emotional he makes them put up a smile, everyone in each world practically loves the guy. The only one who I think can possibly hate him is the Organization, give or take a few. Loyal, nice, sweet, yet cocky, can act rash, and he has his share of problems. Not to mention, he can really kick serious ass, literally, and can pwn you hard. He's evolved as a fighter and person, compared to KH1, and has better abilities. And to give fangirlism here; he's freakin' hot as hell.
Sora period.
