Matter of opinion. Bleach has more mature storylines--Ichigo starts out at fifteen, while Naruto begins at age twelve--and stylistically looks different from the orange-and-blue wearing shonen hero Naruto resembles (Naruto and One Piece both are hugely influenced by Dragonball Z). Naruto's message, however, is clearer to understand--never give up, cherish the bonds you make, and peace can be had if one works for it. The Naruto characters have a personality and Kishimoto describes the persons and the story in a credible way, with many sides of the story. And also the persons change and matures and bad things happen, there isn't always a happy ending but still, the story never is completely sad, there's always humour so I think naruto is better but that's just my opinion.
