I do not watch either of those two, I do not read any of those two. I think there is better anime and manga than those, but everyone have their favorite. I like the world of Bleach, but the persons in Naruto is better, I think. More deep.
And if you want to participate in this, please make a longer reply than "Bleach" or "Naruto". Give an explaination for your choice.
Bleach used to be much better, but after ep 63 everything went wrong.
Get to watching more bud. After the Bounts series, it goes back to Aisen again, and things aren't looking up for the poor chaps... *gets to watching ep. 190*
The original storyline for Bleach was a hell of a lot better than the beginning of Naruto, though that changed when Bleach finished it's first arc and started it's next one and Naruto went on to Naruto Shippuuden.
