Naruto in all scenarios, even the lesser characters are developing powerful techniques.
Round 1: definitely Naruto.
Round 2: Not entirely sure, but leaning towards team Naruto. Obviously team FT get stomped.
Round 3: FT wouldn't go down so easily this time, but would still lean more towards team Naruto. Don't forget, Naruto could also pass on Kyuubi chakra to his whole team to make them uber if he wanted.
