Sasuke had to start up from 1 tomoe.. all the way up to EMS.
Sharingan came from the juubi right? 9 bijuus = juubi right?
Fanboys nowadays.
OT: To the topic is i call it neutral as of now, we need more feats from both of them, i know for a fact that they have more power than they have displayed so far, maybe before she gets sealed we might get few more jutsus from sasuke and naruto.
Naruro got the strongest tailed beast sealed inside of him since birth..
Every time he nearly died Kurama would come out to give him a massive
Powerboost. Later on he literally got handed 8 other biju's + Some sage chakra.
There is a huge difference.
