For me it is naruto. The story development as well as the characters growth is unparalleled when compared to one piece and bleach. One piece is by far the funniest one, but i feel like they take forever just to get the battle actually going in their arcs. having more episodes doesn't make a manga series better than another. it is the content that matters. naruto progresses a lot in each manga where as onepiece and bleach just tend to drag on at the same pace. Bleach was fantastic in its soul society arc and the aizen war. Onepiece still holds the best war. Naruto holds the best overall progression.
I've only watched the first season of Naruto and haven't ever picked up Bleach, so I can't say much about any of them being better. But I can say that I absolutely adore One Piece with all my heart. It started off slow, to be sure, but Oda's built up his story slowly but surely into a beast of a tale. It's just a brilliant, nuanced masterpiece.
Since One piece it's just a tired to see, so much useless episodes... I mean, well.. all those 3 animes have useless episodes!!! But if we are talking about the manga, I would still go with Bleach. I love the characters more than on Naruto/One piece... but I must say that on some times I like Naturo more, mostly becouse they do kill main characters *mehahahaha* while on Bleach, they always add new characters depending on what they are doing.. there're a lot of secundary characters! You can't even remember them all...
i like bleach the best out of these. i watched one piece and naruto when i was younger but i didn't hold onto them for very long like i did bleach :c
imo bleach has a really cool storyline, but if you're watching the anime theres a billion fillers but that kind of applies for all of them :X
I started watching Naruto when I was still a kid. Started One Piece when I was in college. And started Bleach after I graduated.
I like OP the most, but still enjoy the other two. OP simply cracks me up, and some of the islands are awesome. I really like the Skypiea arc, made me want to go there too if it exists xD
