I think naruto as of now is much more strong than Sasuke is, the manga stated that they were equals after the fight with danzo, but after that Naruto is much more stronger.
He has SM mode KM mode and now as of CH 570 he has the full chakra of the Kyubi. Also he is now the fastest shinobi ( although naruto cant control it fully as of yet), we already see two instances where he is called the yellow flash, sasuke's EMS wouldnt be able to keep up with his speed, and naruto's rasenshuriken could rip sasuke's susano... and the only weakness naruto had that was genjetsu, kyubi would help on it..
