I don't mean to be picky, but even though One Piece is completely unique and ten times better than the art in Bleach or FMA...they're really not that stereotypical anime to be honest (although it's kinda hard to tell unless you see the manga illustrations, the anime ones do indeed seem stereotypical anime). They have moments that are often used in anime (or morely, anime cliches) but I find both of the styles to be quite unique, especially Bleach's even though Bleach is really really bad in terms of characters and story. Matter of fact I know quite a few people who read Bleach just because of the unique art style, lol.

I mean, really, Cowboy Bebop is more animu than both FMA and Bleach in terms of art style. >_> I'm sorry, it is. There's nothing wrong with that, but I've seen Cowboy Bebop's style tons of times.

That being said, I think the two manga artists who really stand out in terms of superb art that excels even the art in American comics is Kentarou Miura and Takehiko Inoue. Both are just excellent in just about every page of manga they draw. Both, however, did have a rough start and developed their styles over time (meaning, they were mostly okay at first, very detailed, but it wasn't the best, but nowadays it's completely different and I could honestly call these two guys some of the greatest artists in any comic book), and not all of their stuff is the best in the world (however both of their life works are pure masterpieces) in terms of story and whatnot.

Tetsuo Hara also really stands out as a very detailed and good artist although I wouldn't say he's as great as the two ones listed.

For my other two favorites...Naoki Urasawa simple for his awesome facial expressions and emotion, and Hirohiko Araki for his unique, awesome, and detailed character designs.
