Kenshiro 10/10 and that's Ken before he even mastered Musou Tensei, that's Ken before he fought Souther and Raoh. Ken who fought Shin would be able to own this match with one punch.
Bane does not have Superhuman durability, even on Venom he has been seen getting hurt by punches from people like Batman who is peak human if not a bit above that. He also doesn't have superhuman stamina either. It's enhanced but not superhuman, Bane can not fight for days without showing any signs of getting tired. I mean the fact that you even state that Kenshiro is Superhuman across the board while Bane isn't superhuman should be enough to state that Ken would win.
