Sennin Modo Naruto vs Mangekyo Sasuke most likely ends in draw, since it was stated that if the two fought they would kill each other.
So it would come down to how much Hinata and Sakura can support Sasuke and Naruto. Hinata adds some greater perception to team Naruto, but nothing major considering Naruto already has sensing in Sennin Modo. While on the other hand Sakura offers great support to Sasuke. Sakura can provide him with poisoned kunai, sleeping bombs, and heal him resorting his stamina with medical ninjutsu.
So i'm going to back Team Sasuke
