I was being obnoxious but given the structure of the this, DC coming out on top so much actually makes sense. DC Heroes tend to be just a little stronger than their marvel counterparts (or a lot stronger). Street level - the character that almost defined the genre is DC, so he gets in the top just be being Batman. Marvel doesn't do teen sidekicks, and have not done legacy heroes until recently, so that gives Marvel less bench strength in choices in the Teen tournament.
When the jump to unlimited - Marvel tends to go big. DC has people like Superman, and unless he is the early 80s pre-Crisis Superman, Pheonix would take him out. Franklin Richards and others that would show up in unlimited class - the DC powerhouses like Dr Fate likely can't stand up to them. If the GLs are in that class, so would Silver Surfer. Mentalists - the Martian Manhunter or Saturn Girl can't hold a candle to Prof X. To be honest, depending on who all gets in, I expect Marvel to take most of the top spots of unlimited class.
