All team 2 has to do is take to the air and they get to double team Thor. As much as I respect ol' goldilocks, he's going down hard against Supes and WW. That leaves Herc who they can take down at leisure from range.

Team 2. Both members have superior speed and flight capabilities. Diana can use her equipment to take Herc out of commision while Supes can stalemate Thor (as much as I loath to admit it) until Diana joins in the fray.
Gotta go with Team 2. While Thor could make for the win over Superman via magical power, Supes could hold out under any normal circumstances long enough for WW to get involved, after she takes down Herc (which she has historically been able to do whether Herc was "merely" a demi-god or -- in later DC continuities -- a full god, which would put him on par with Marvel Herc at his peak). Team 2 7/10

Herc and Di are pretty similar, but she has flight, speed, and a *lot* of gear. The tiara is especially nasty in a to-the-death match, which puts it above a slugfest and introduces the chance of inflicting major wounds quickly.
