Tbh, I still believe Sasuke to be stronger or at best evenly matched with Naruto. He lost because he decided to stop fighting because of feels.
Sasuke is proficient at:
- MS techniques
- Rinnengan techniques
- Yang chakra
- He can technically learn any jutsu with both of his eyes and any element
- Vast chakra reserves
He's too OP and well balanced.
Naruto has more of a raw power and physical proficiency but he lacks in other areas.
