Who is the real super leader Captain Marvel or Superman?

Could it be that Captain Marvel and Superman are twins, they look a lot alike. If i can remember right they did fight once and Superman died. But hey you tell me who is the bigger beast.Who is the real super leader Captain Marvel or Superman?Captain Marvel is the bigger beast. Superman has all of those powers and he still gets his *** kicked which is a shame. He is only SUPER when he is fighting humans.
