mutants have a far more realistic stake in the Ultimate universe. Ultimate Spider-Man, Fantastic Four and The Ultimates all talk about mutants, "the mutant problem/situation/agenda" and have crossovers constantly. With 616 mutants often seem almost out of place.
I am one person who loves that Marvel doesn't have control of X-Men. I like the separate universes. They function better in my opinion. X-Men can focus on a lot more characters when they are on their own. Marvel can focus on a lot more characters when they don't have to worry about mutants.
