Kakashi never told that Byakugan surpasses Sharingan. It is a misconception.

So you expect us to believe that 3 tamoe sharingan is better than x-ray vision, telescopic vision, 360 degree version, chakra perception, and tenketsu perception? Riiiiiiiiiight! Keep trying buddy

3T sharingan= Genjutsu> all other byakugan abilities

 

[Aikor]

Byakugann is still better than base sharingan either way

Interms of vision yes but interms of Fighting no just no.Genjutsu ftw!

 

[JStar King]

Let's see what a Byakugan user can do against an MS user. Amaterasu-Susanoo-Tsukuyomi vs Gentle Fist. Hyuuga might think they doing something until they become BBQ or pimp smacked with a Susanoo sword or get Jigsaw'd in a Genjutsu. Yeah, the Byakugan is an awesome Dojutsu, but I'm sticking with the Sharingan because it's stronger as it evolves.

DEM UCHIHA!
