Hasn't Batman also, in some media, gone blow for blow with Superman-level opponents without dying? Like, he's not as strong as them, and superhuman strength isn't technically a superpower he has, but...
No. Even if you could match the current fictional character's tech and computing power and budget and incoherent physical strength, those really are not what make Batman Batman. It's the intellect, the iron will, the sheer level of badassery that can only be achieved in fiction where an author has him appear behind the villain just to show what an impossible nightmare Batman truly is.
Being able to pretend that he's Bruce Wayne sometimes certainly helps, though. He's a good actor.
