Superman has super speed. He could've totally restrained Batman before in the blink of an eye, and then attempted to negotiate with him. Batman would be completely immobilised (anyone who's ever been grappled will know how immobilising it is, imagine how much more so it would be if your grappler had super strength!) and incapable of using any of his weapons against Superman. The idea of Superman getting into a punching match with Batman made no sense to me.
