Lord Chaos, Master Order and In-Betweener is Team 1
Eternity, Death and Galactus is Team 2. Galactus is at full power.
I say that team 2 has the upper hand. Galactus held his own against in-betweener while not fully fed and eternity was stated by LT to be the strongest cosmic being after him (If i remember correctly).
This would be close as they are counterparts after all.
