( i wasn't sure who was on either teem currently so it's a copy/paste affair, if anyone is more in tuned put up the real roster)

new mutants. mostly due to a bigger roster.

TL; DR.

It's Titans vs New Mutants, and then there's both Magneto and Prof X on the mutant side? As well as greater numbers?

Gonna go with the mutants.

they're just trainers however (per wikipedia), i'm not sure how much involvement they have in missions like say the avengers academy trainers do.

But they're in the fight.

The Titans do have three powerhouses, Osiris, Superboy, and Wonder Girl, but Osiris is a newb, and I don't think SB and WG even working together could take on Mags very well.
