Who's the best comic book artist in the world?

[JJ McKool]

I like debating it, cuz everybody has an opinion, and there is no objective truth. That said, who's the best artist in the world, in your opinion? I think I made a thread like this before, but this time, state your reasons, and feel free to debate for or against anyone. Pretty much no rules here. Alive or dead.

I'll probably defend somebody or choose somebody later, but I'm thinkin about it right now.
