Actually, Surfer would ruin Apollo. Warlock/Apollo would be a good fight, and I'd actually pick Warlock.
Infinity Watch definitely has the potential to take out The Authority. For me, it would come down to how much the Doctor could affect Thanos/Surfer/etc. In theory the Doctor is above Skyfather and could probably beat them...he could travel time and give the Authority oodles of prep, turn most of IW into monkeys and trees, etc. But to be honest, he's never displayed that sort of raw brutal power...and he definitely has shown a limit to his power level in the comics. Part of it is his own inability to fully harness his powers, part of it is his drug addiction (hehe).
I would say Infinity Watch takes this fight, even though I'd be rooting for the Authority. Thanos and Surfer are beyond anyone in the Authority except the Doctor, and the Doctor hasn't had to face someone as fast and deadly as either of them.

Great point. Given this fact, the Authority is screwed. No one else is even near Surfer, Thanos, maybe even Warlock in terms of power besides the Doctor.
