I'll bite. If it's Pre-FP versions...
I'm giving the DC ladies the win here. Supergirl and Wonder Woman are the class of the field, and the team has a large feat pool to draw from.
Black Vortex Gamora seriously underperformed, Unum existed for one issue, and Carol is likely the weakest link on either team. I can't see them winning a forum fight.
DCnU versions, I don't know. I only recently started reading it, and haven't gone far.
