Sure, in terms of ability, it was great. Difference being, the Biju aren't a reliable source, Sasuke had access to them at the moment, but might not have had access to them in a different setting. Naruto however always has access to the Biju sealed inside him, Sage Mode and earth's energy.
The fact Naruto with 0,5 Biju matched Sasuke with 8,5 Biju, was kinda weak. The Biju weren't really weakened either. They were all stored inside Kaguya, whose Chakra was far beyond even Madara's, who became Juubi's Jinchuriki. But if you wanna play that card, Naruto's 50% Kyuubi also was weakened.
All I know is their adult versions are even stronger, yet got trolled by kids or kids possessed by aliens.
Bro, what the heck is this.
