How can that be a moot point when that's how DC bases it's characterizations? If Superman outsold Batman by that much then Batman would get punked by Superman all of the time. We would all laugh that a human with gadgets acts like he is God. Batman would become Blue Beetle with a better costume. The fact of the matter is that you can trace the depictions of Superman and Batman interactions through the years and see exactly when Batman became "cool" and the flagship of the DC line. It's not only not moot, it's the answer to the question
