Sharingan > Byakugan
1. Visual ability.
Sharingan is able to see chakra ( obito ) predict movements, follow enemy at high speed, copy taijutsu and Ninjutsu. ( genjutsu was never shown to be copied, and I'm sticking with Manga facts)
Byakugan is able to see Chakra and chakra points, it has 360 degree vision.
In visual ability Sharingan wins. Ability to see chakra points is useless to Sharingan user because they do not focus on taijutsu only but are capable in all 3 categories. Sharingans visual powers allow its user to copy new Taijutsu and Ninjutsu, and is also naturally powerfull at Genjutsu
2. Potential
Strongest Sharingan users - Madara, Itachi, Sasuke, Obito.
Strongest Byakugan users - Neji, Hinatas father, Hinata, Hanabi.
Sharingan: 1tomoe - 2 Tomoe - 3 Tomoe - MS- EMS
Byakugan: x
Sharigan users have alot (100x) more potential than Bakugan users.
3.Special Abilities.
Sharingan: learn any non KKG Ninjutsu, powerfull at genjutsu, Amaterasu, Tsukuyomi, Susano, Kamui, Eton release, PS.
Byakugan : 360 field of vision, Rotation, 32 palms, 64 palms.
Sharingan takes this one.
When I see people saying Byakugan is better than MS I wonder if we are reading the same manga. Byakugan is barley able to keep up with 2-3 tomoe Sharingan. Let alone be compared to MS.
I'm not an Uciha fan, quite contrary, only uchiha character I like is obito, but it's obvious than Sharingan is light years ahead of Byakugan. Hyuga fans are truly becoming delusional.
