I say Team 1.
None of Team 3 can hurt Konan wo Katsuyu.
Mei blocks vision, Hinata can't see when her eyeballs are melting.
While in mist(no acid) Ino can mind transfer to her opponents as they won't see it coming.
Hidden mist shuts off Hinata's byakugan advantage making her neigh useless while Ino still has mad sensor skills to find where all of team 2 is.
Ino mind transfers with konan and goes through the mist in paper form. Team 2 won't notice konan coming until it's too late. By the point they notice, they're wrapped and blown to bits.
Simple, team two have two kage level shinobis and one very good back up. No one in team two can't touch Konan and Mei's abilities will also be very useful. Team one win with mid diff, even if team two have Katsuyu.
