Hmm, well, this depends. Bleach, like Naruto suffers from "filler episode" syndrome. However, I find some of the Bleach fillers to be quite good, like the whole Zanpakuto arc.ChromeAlchemist said:Agreed on One Piece (anime, don't read the manga), I don't read either Bleach but I've been planning to, I only watch it. Is it worth it?
The anime is catching up pretty close to the manga, and the fighting is more fun to watch in the anime.....buuuuuuuut the manga doesn't dick around. Still, the anime answered a lot of unanswered questions the manga left open, so personally I'd just stick with the anime.
(If there is a manga to read, it's one piece. I don't even think the series is halfway done yet.)
