Naruto's speed alone is enough aswell as clones and a rasengan blitz or rasenshuriken ... yata mirror cant protect you 360 degrees and naruto is to fast for totsuka and amatersu so naruto takes this

Kurama (feat Naruto) might win
but you can never know what kind of forbidden uchiha hax jutsu Itachi's gonna pull out, that guy is full of surprises so it can go either way... if we go only by feats KuramaNaruto wins
