I think you guys are forgetting that though Batman has no super powers, he has gone up against bad guys who do and he's whipped their behinds. Spiderman has the strength, agility, spidersense, and web shooters, but Batman worked years to be a one of the greatest martial artists of all time. For this reason, I think that Spiderman's strength may not be too much of a factor since Batman may be good enough to use his strength against him if that's all Spiderman is relying on. As for the other powers, be serious, Batman wouldn't try to go against Spiderman one on one if he had the time to prepare properly, he'd built some sort of suit to even out the playing field or something. If he didn't have time to prepare, I think that Spiderman's agility and speed would help him more than his strength. If Spiderman takes his time and keep his distance, he would eventually wear Batman down. There's always the chance that Batman will think of a way of winning though. He's got no superpowers, but he's also a very smart fighter. I think this would be a tough call and it would depend on the situation on who would win.
