This is tricky, given the combination of characters given: Team 1 has the energy output advantage and a magical edge, but Team 2 has a massive speed advantage, as 3 of them are massively fast, and the 4th (J'onn) is not far behind, while Team 1 "only" has Makkari and Adam in that relative department (more Makkari than Adam). I don't think it would be the stomp indicated so far, though I will go with Team 1, 6/10 or so, with the wins Team 2 gets being largely from relative speed blitzes.
