Well I like many many many DC hero costumes better. But as far as soley in the Marvel universe. I'd go with the Ben Reilly Spider-Man costume. I think it was much more "slick" and basically looked fucking cooler.
Also I say Ben's costume instead of Spider-Girl's costume cause I do think it looks better on him then on her.
After that the first Hobgoblin costume has always been a favorite of mine. Definitally one of my fav villain costumes.
