Iron Man is cool. Just not the coolest.

The X-Men will always be awesome.

I'll give a nod to MILF that Supes can be good if the story is written well, but with his type of character doing that is HARD, and creating a long term story arc that stays compelling is almost impossible. He's a great concept that is just difficult to keep interesting.

Batman has always been interesting to me, and probably always will.

Spidey will always be my favorite. He has all those qualities that myself and so many other awkward nerds like to believe they have too. It really is like watching what we'd like to think we'd become were we given his powers.

What is the best hero vs. villain story arc?

Spiderman against Venom and Carnage will always be one of my favorites.
