I give it to Ultimate X-men as well. Don't let my signature make you think I'm biased. I really believe the X-men would win this fight.
Don't get me wrong though, I think it would quite the match. These are all top-contenders here. But the X-men have shown, even in Ultimate X-men itself, that they can easily handle Scarlet Witch and Quicksilver (And he's my very favorite X-men character), so they won't pose much of a threat.
And yea, Ultimate Colossus is mad strong now. He can easily take a few members of the Ultimates. And then you've got Jean/Phoenix. Not too much to say there.
And even Cyclops's beams are much stronger in this series. And honestly, I've never seen Iceman so hardcore before. He's actually using his powers very efficiently, which makes me very happy. Beast, too, is another of my favs in this series, actually proving his worth among heavyweights like Colossus and Jean. Beast could probably take Captain America. I think so. Beast is quite the tactical one himself, don't forget.
I think it would be an awesome fight, but the Ultimate X-men come out of this one the winners.
