Tough battle to decide.
Erads and Supes could engage in T-vo (which could go either way since they are both good at it) leaving Surfer to engage Preus and Superboy. Preus doesn't have a weakness to kryptonite and we don't know if he weakens to a red sun. His suit also compensates and adapts to many things on the fly. With Superboys help, they should overpower SS.
Then again, the combination of Power cosmic AND T-vo on 1 team sounds frightful...
