IMO I bleieve that Naruto is not only stronger but more skilled than Sasuke at the moment. Why? Because Naruto has tons of previous experience with his new powerups. Naruto was already a Perfect Sage and Jinchuriki. So he not only has loads of practice and battle eperience with both but he has practice and experience with both of them fused together. Now that Naruto is using some new form of Senjutsu which is basically an upgrade to his already perfect Sage Mode that just makes Naruto durability, speed, sensing area, and power of ninjutsu levels above what they already were before. Even with just his regular Sage Mode he was able to put a large dent in a mountain with his Wind Rasenshuriken. With his fused mode he was able to obliterate a mountain completely. Now that he has Juubi chakra and an updated Sage Mode fused I believe that we are only seeing the tip of the iceberg on what he can do. He currently has a hunungous potential as far as what he can do, sense, and create now that he has access to unlimited bijuu chakra, senpo chakra, and unlimited skill in chakra & shape manipulation.
I don't want to take anything away from Sasuke but right now Naruto not only has power over him but also experience even with his new powerup. I want to know what kind of Senjutsu Hagaromo gave to Naruto and if doesn't have a name is it the original Senjutsu of the ninja world?
