The GS had a really good showing, and they have a duplicate of Superman, Flash, J'onn, and a Fate light character, as well as a Batman clone. The Authority has a few more weak links I think than the GS, so for now I give this to the GS.
I mean Sun God just whupped the Hulk (and Sun God really exerted himself before he even fought the Hulk dealing with those Black Priests or whatever they are called). Boundless literally dismantled IM. It looks like Jovian is about to beat Namor. And Spectrum's shield was powerful enough to withstand Sun God unleashed.
