Well, here's my two cents...
The original Green Lantern Corps were disbanded for the sheer fact that they were waaaaaaayyyyy too strong.
The Silver Surfer has the Power Cosmic, not Galactic, (you may be thinking of his archenemy, Galactus, Devourer of Worlds) and is nigh indestructible. (although he's got no real personality)
Mr. Fantastic did NOT marry a hot younger woman anywhere except in the crappy looking upcoming movie. He actually married a woman that's around his own age, not Jessica freakin' Alba.
Wolverine is a great superhero. He's hundreds of years old, may be Canadian (woot!), and has super regenerative abilities and an Admantium skeleton!
Superman rocks, albeit he's allergic to Kryptonite, and loses his powers under a red sun. (See Superman vs. Mohammed Ali - great comic!)
Overall, however, I've gotta go with a non-superhero for the best of the best. The Punisher is, hands down, my favourite comic hero ever. He pulls no punches, is completely onside with his 'revenge' angle, and has no fear in showing badguys a really terrible time. (Of course, he's not politically correct - but hey, another reason to like him!)
