I was thinking the same thing and pretty much it would all depend on which suit Spider-Man was wearing.
Original Spidey Suit - Batman or spidey (Batman would counteract spidey's basic moves, but spiderman could be faster and punch out batman)
Venom-Spidey Suit - Batman (find someway to use sonics)
"Bionic Commando Arm" Suit - Spider-man (increased healing factor)
"Octo-Spidey" Suit - Batman (Batman would use Spidey's arms against him)
"Six-Arm Spidey" - Spider-man (Unlike the octo-arms, spidey would have more control over them)
Hulk Spider-man - Spider-man (Spider-man as strong as the hulk... 'nuff said)
Spider Carnage - Batman (See Venom-Spidey)
Spider-Phoenix - Spider-man (Spider-man with the powers of phoenix...)
Cosmic Spider-man - Spider-man (Same as Spider-Phoenix)
Civil War Spider-man Suit - Batman (It's tech, batman could possibly hack into it)
I think that is every form of Spider-man suit that Peter Parker has worn, and remember, all these may be wrong, it depends on who writes the story
