Naruto/DBZ yes, OP nope.It's objectively the greatest anime of all time. Far and above any Shounen (which includes Naruto, DBZ and One Piece) without even trying. It has great fighting scenes, but that isn't event the best part. The story captures you in a way no other Shounen really can do. And you had better prepare yourself for a lot of pent up sad feelings, because it's one story that will do that to you. Remember to watch the Brotherhood version though. It stays true to the manga.
OT: Yes lol, it's much better than Naruto. Make sure you watch brotherhood though.
