spiderman movies are more entertaining. batman movies always seem to come off as cheesy in an unintentional way, whereas spiderman movies are fully aware their chessiness.
in an actual fight i would say that spiderman would win. batman doesnt seem agile enough and always seems to rely too heavily on the conveniently placed explosives/traps/heavy objects/ramps which seem to surround him as well as his brute force strength which alone is not enough to overpower the sheer awesomeness of spiderman with his evasiveness and projectile attacks.
Spiderman 1 and 2 are fairly cool, but Batman Begins crushes them. Plus The Dark Knight looks redonkulous. The first two Batman movies are also pretty solid. Batman & Robin sucks balls and Forever is fairly meh, but the good outweigh the bad. Plus Batman just rules.
