I personally prefer One Piece.
Naruto is good and all, but it only recently broke out of its parallel to 666 Satan.
I don't watch the 4Kids version of either. They suck. The only episode I've seen in English was the one where they introduced Sanji. Ruined the scene where he beat the hell out of that Navy officer. In the manga, Fullbody was losing blood at an alarming rate while Sanji pinned him to the wall. In the 4Kids anime, he was just holding him up. Not to mention Sanji's cigarette was switched out with a loli-pop. Seriously.
