I liked Bleach well enough at first when it was episodic but once the Soul Society arc got going I lost interest. The Soul Society arc tends to be what everyone considers the peak of the series, and it's what lost my interest so I've never been exactly eager to return to the series. I will attempt to read the manga at some point though, because maybe it was just the typical anime adaption pacing that killed Bleach from me. Though I know various spoilers about Bleach and the general consensus around it leads me to believe I won't end up liking it regardless but I'll read the manga one day.
Naruto wins easily, I actually watched the anime adaptation of the first half almost fully (I stopped shortly after Naruto lost his chance to find Sasuke because he farted on a bug) but I have read the series entirely in the manga. And like, I'm not overwhelming positive on it or anything, I'd give it a generous 7 but the series does have a lot of strong moments, especially earlier on. Worth noting, Gaara vs. Rock Lee was like the hypest fight when I was a kid.
