Kenshin. He's almost as fast as light, and not even the Force can match the raw awesome and the secondary vacuum effect of the Amakeru no Hirameki. Darth Vader is also slow, a freak, mentally imbalanced, and slow. Kenshin is fast. He fights blind (Shimabara only). He gets hit by hammers from hammerspace. He had to fight Enishi, Shishio, Jin-e, Saitou, and even Aoshi. You tell me who wins now.
