Don't really recall just how strong the SJ members are but the typical Asgardian is in the 30 ton range, I would assume the W3 are stronger. They are supposed to be more resistant to all forms of microbe/disease and I think Fandral is quicker than the average Asgardian as well. The Asgardians should be much better combatants overall.
W3 for the win 8/10.
That woman in the back, between Ch'od and Corsair, that's Cerise. Is she a member? She's like a mini Quasar (energy blasts and energy constructs). If she's on the team they have a chance, otherwise Warriors Three stomp.
