If you only watched 20 episodes of One Piece and concluded it's shit, your opinion isn't worth anything. If you watch 20 episodes and already start reviewing the series, that's like reading the first 2 pages of a book and concluding that the book is shit..
As someone who has watched, and read both series (a few times at that), One Piece is better than Naruto. There might be an arc or an episode where I feel that Naruto was better than One Piece, but overall One Piece is better than Naruto. Right now for example, Naruto has reached the peak of the war, awesome fights are going on and stuff, while One Piece is still at the stage of the arc where they are setting up everything for the epic fight at the end of the arc. That's why I thought this weeks chapter of Naruto was better than the chapter of One Piece that came out this week. It'll shift around in a few weeks, where I feel like One Piece chapter is better than Naruto chapter, because the fighting will start in One Piece. But looking at the overall series, One Piece is better than Naruto.
Also Moon eye plan: Your opinion on One Piece ain't worth shit for the reasons stated above. You haven't seen enough of the series to judge it. Also, calling someone else "kid" doesn't make you seem more mature or it doesn't make them seem less mature either.
You posting the same thing 3 times in the same thread because it was ignored the first time, just makes the 2nd and 3rd post spam.
