Hmmmm....If I was to do honorable mentions, then they would be:
Yu Yu Hakusho- Not as good as the anime adaptation that improved on its story even more, but it was still great on its own, and it is the whole reason for why the anime even exists, so this is what started it all. I also enjoy it more than HXH, personally, but the reason for why I didn't list it in HXH's place is due to the manga's extremely rushed ending, which ticked me off quite a bit. The anime really improved on the Three Kings arc by miles, IMO. Still, I'd take YYH over most modern WSJ series, any day.
Hikaru no Go- An extremely fun and addicting manga that made what originally seemed like a boring concept extremely interesting. That, and it had likeable characters. My one problem with it is that it ended up being way too formulaic and predictable, but sometimes that's not such a bad thing, and this manga sure does prove that point.
I have to agree with this. In all honesty, I have mostly viewed Bleach as being an extremely generic, derivative, and very formulaic shounen series that just goes by what we've already seen in a lot of shounen manga, rather than just YYH or any one manga alone. Its really a shame that Tite Kubo couldn't continue with his other series, Zorabie Powder (which I felt at least had some more substance and unique-ness to it), and instead got his long-running series to be Bleach which is basically like standard battle-shounen 101, to me, personally.
