Ken won in the alpha series didnt he. His ending were he beat Ryu, gave him the headband, in later games, he was wearing that headband, so you can assume that ending was cannon right?

ken didnt want a unfair fight, that is why when he noticed that ryu wasnt focus on the fight he gave him his bandana for him to remember that he has friends and that he will never be as akuma
Evil Ryu has a lot of problems. Inability to focus, susceptible to blows... Normal Ryu would have a much better chance of winning, but for all intents and purposes the two were even, despite having different advantages over one another (Ken's Dragon punch mastery, Ryu's fireball mastery, etc. Ken tends to go berserk more often and has longer reach, but Ryu is a cool fighter and probably has more practice.)
Actually, thinking about it, this can go either way.
Ken and Ryu are equal even as of SF II, which takes place well after ALpha series. And evil Ryu technically doesn't exist, since Ryu rejected the Satsui no Hado.
I think Ryu would win becuase he lives for the fight and has spent most of his time training, Ken on the other hand just trains to keep up with Ryu and probably wouldn't be as strong as Ryu up to 3rd Strike because of Eliza, Mel, and Sean.
