To be fair, OP only said that Naruto has Kyuubi chakra. That could mean Six Tails Naruto is not off grid.

Anyway, I think Naruto and Sasuke win. High difficulty. And at least one of them's gotta die - I'd wager Naruto - since he's less equipped to deal with Itachi's Tsukuyomi and doesn't have enough TB control to counter Amaterasu. Sasuke's got Kirin and the fact that he and Itachi are bound by blood means he can bypass his Tsukuyomi. Via Orochimaru's chakra, he can shed his skin to alleviate Amaterasu and he can create the perfect weather conditions to execute Kirin.

Thing is Naruto at this point in time was quite weaker than Sasuke. If you'd said SM Naruto, then I'd give it to the Team 7 duo with mid difficulty, no casualties at all.
