Include Hebi Sasuke on Team Taka and give Team 7 a base Naruto to make this more fair.
Sasuke = Kakashi (more or less, they have similar abilities...this is what it really comes down to)
Juugo < Sai (CM2 just too stronk for Sai to take down with his sealing tiger, but Sai has the aerial advantage and can hold him off)
Suigetsu > Base Naruto (liquification pretty much trolls here, but clone spam means Naruto can at least hold him off for a while)
Karin < Sakura, but they will mostly be playing similar support roles as the medic-nin of their respective teams
Overall I'd give it to Team 7 mid-high diff since Sakura can act as a chakra battery for Kakashi and remotely heal her teammates via Katsuyu as well as enter the fray herself (due to Byakogou) unlike Karin who would just get killed in the crossfire.
Without Naruto and Sasuke, Team 7 stomps.
Kakashi and Sakura would possibly solo this.
Team 7 stomps.
Sakura? Naw. Karin was putting up a better fight against spiral Zetsu than she was.
Sakura would one shot Karin, bruh.
Unless Karin smack Sakura with her chains first. Those chains>Sakura's punches.
