I'm calling a stalemate on this one weapons or not these guys are pretty much equals IMO. No Batman does not know more styles than Panther. He knows just as much as Batman. I mean the guy has been training since he was a child and even has some styles that only the people in Wakanda know. And no Panther does not have a healing factor. This is as even as you can get in a Marvel vs DC battle and actually the best fight IMO it can go either way.
