bahha, Mangaka's I've read more than two manga's by them and i really liked?
probably adachi, Rough is one of the best stories around.
also Rumiko, I'm a sucker for long mangas.
Togashi is also cool, though I only read YYH and HxH.
Hiroki endo has god-like skills.. I really have to start reading Eden.
Kitoh also has some skills, Uzumaki was good, and so is his short stories gaiden, and you can't forget Narutaru.

Other than berserk, what else did Miura work on? I mean long mangas (not shorties like Japan and King of Wolves).

I can't stand Amaretsu, or the guy who did I's and Zetman.

but the one and only is Toriyama.
