Who would win Avengers or x-men?

Personally i think X men will win.

Magneto can easily take down basically anyone with metal in their arsenal ie. Iron Man, captain America, Black Widow, hawkeye etc... and Emma frost can take down anyone who has a mind really (not sure about the hulk) and with Cyclops, Juggernaut, Ice man, Storm and all the other x - men backing those two up they are an unstoppable force
