Surfer vs Ronan, Thor vs NP/Quasar. Ronan would go down way too quickly. It becomes 2 vs 2 in w/c case duo wins. Duo wins 10/10.
Surfer vs Quasar, Thor vs NP/Ronan. One of the fights where trio has a chance. Quasar does pretty good vs Surfer and NP/Ronan combo might be able to take down Thor a tad bit faster than Surfer would be able to take down Quasar. The one matchup where I give trio at least a 6/10.
Surfer vs NP, Thor vs Ronan/Quasar. Good fight. Another matchup that is a bit favorable for the trio. Surfer would take out NP but it won't be quick. Thor vs Ronan/Quasar might be a split or slightly favorable for Thor. Trio would get 5/10 at best here.
Surfer vs Ronan/Quasar, Thor vs NP. Best chances for the trio. Quasar and Ronan would work perfectly to neutralize Surfer and NP can certainly keep Thor occupied long enough for this to happen. Trio wins 7/10.
Surfer vs NP/Quasar, Thor vs Ronan. Ronan goes down too fast. Duo wins 8/10.
Surfer vs Ronan/NP + Thor vs Quasar. Good fight, will have to give to duo tho. Surfer alone can pretty much tool either Ronan and Quasar. 2 v 1 he can stall em quite a long while IMO. Long enough for Thor to take out Quasar Duo wins 7/10
Overall, I think duo has a better chance cuz there are some pretty bad 2v1 matchups here (Ronan would be weak link) for the trio that would result in a 2 v 2 w/c the duo can soundly win.
