Sage Mode Naruto vs MS Sasuke - The Real Winner 

Naruto was written in such a way that protagonists who often showed great feats always succumbed to a perfect counterpart, for instance swap naruto for sasuke in the 5kage summit and same for the pain fight then i think they both die so it has that inherent style so its always hard to theorise a vs battle unlike in something like Dragonball where power scaling is linear . In Naruto certain abilities are more potent against certain characters and weak against others its not tit for tad

Let’s gooooooooooooooo!

Taka sasuke < hebi sasuke < sage naruto < 5 ks sasuke < kcm1
