Spiderman averages ten tons or so of lifting power on average, though he has been known to exceed that under duress. Basically the normal mom lifting a car type of scenarios. So physical strength wise, bane has an edge over spiderman, almost certainly in durability as well. And one of the biggest reasons venom is a tough fight for spiderman is because his spider sense doesnt work on him, which is a major handicap for spiderman. Bane has no such sense that he couldnt use against venom. Venom is 2-3 times stronger though.
