hard to make a decision because we know lil about kabuto other then his edo tensei and we also know lil about sasukes ems as there was said to be a new jutsu awakened with ems and we havnt seen it yet but based on all knowledge given naruto and kakashi and gai could take tobi and i based one my knowledge sasuke and itachi could take kabuto with chakra to spare and after that five kages could hold madara until the uchiha brothers were free and then all 7 could prolly take madara
i understand there are alot of unknowns in this battle and to make a choice is basically impossible but my assumtion is that team 1 would win
Hmm... this is a tough one.
I think Team one wins this one. Naruto could take on Tobi while the others deal with Madara and Kabutomaru.
That's my opinion anyway...
