Who're you talking about with Naruto and Kakashi's equal?
Going by feats, part 1 Sasuke is basically a much weaker Kakashi-copy: A smart Taijutsu-fighter using Sharingan, Chidori and some mid-range Ninjutsu. Just that Kakashi's base feats are leagues better, his Raikiri is > Chidori, he has more experience with Sharingan and a larger arsenal of Ninjutsu. Plus intelligence and experience way outclassing Sasuke. I can't see the V2 Juuin boost making any difference in that.
