Joe Quesada
Jim Shooter
"I came to the conclusion that the optimist thought everything good except the pessimist, and the pessimist thought everything bad, except himself." -- G.K. Chesterton
Joe Q all the way. Shooter's tenure had a lot of great comics but from pretty much all I've heard it was mostly in spite of the guy.
It comes down to style over substance and there was more substance under Shooter's reign because love or hate him, he was a really good writer and had vision.
Definitely Shooter. I associate him with what was good about Marvel. When he left everything went down the toilet. There are not many Marvel comics in the 90s I liked and let alone in the 2000s. Granted, Quesada wasn't responsible for it all. but I feel he didn't make much of a difference.
