I like Batman more but picked Spider-Man because he has more abilities and the only disadvantage he really has is that he's poor. And his spider-sense gives him a major advantage over Batman since most of Batman's tactics rely on surprise attacks.
I do get a lot of money if I'm Batman, but I think I'll keep the powers instead.
Batman is a lucky rich bastard who can afford to be a superhero so if he goes bankrupt he is no longer a superhero! while spiderman is a regular guy like any of us who have a natural superhero powers so he can still be a superhero no matter what ! plus he flies, I could pay any price to be able to be able to fly so definitely I choose spiderman
