Hmm...that's a tough one, I'll admit, but i think Batman takes it there. He is just a human. Like any other billionaire human, he can only do so much. He has no superpowers, he only has his wits. That is the coolest thing about him, i guess. It's so cool when you have a psychological trial to confront; Batman the Dectecive! That's waaaaay better than just having your amazing powers do your feats for you. The Riddler is one of my favorite villains, as you might guess. Brain power with a pinch of brawn when needed makes for the best possible DC comics could make! Marvel is all about...marvelous heroes. So, it isn't as impressive as someone who does all his own stunts, so to speak.
That is why i would support Batman over Spiderman. But hey, Spiderman is incredibly cool too, but that one brain factor beats him out.
Anyone agree with me?
