Team 2 gets 30 minutes of prep

Titans IMO.

I'm assuming the Titans are Pre-FP.

It's current versions where applicable

Well, then I'd lean slightly towards the Thunderbolts.

DCnU Superboy doesn't seem nearly as powerful as he used to. Granted I haven't read his series for a long time.

^^ He's actually quite formidable, but an evil Superboy just took over.

I say Titans eek out the win.
