well I can't remember, but I only can think of the Byakugan, Sharingan, and Rinnegan...and I mean now it is basically the Byakugan vs the Sharingan since Kishi made the Sharingan evolve to the rinnegan...
I would say the Byakugan is weakest...taijutsu has become totally useless now that every top tier shinobi has a jutsu that flat out destroys anyone attempting to fight them......Meteors, oodoma rasengan, Kirin, Mokuton, Susanoo, Hell Stab, Dust release.
The Byakugan has no way to fight against the Sharingan I mean they can use rotation to avoid being hurt, but you can only spin for so long...
and even if the sharingan isn't a MS the user can still copy the high caliber ninjutsu and use them against the Byakugan user and win from having the advantage of range...the only ranged attack a Hyuga has displayed is air palm, and quite frankly it looks rather weak to me :/
I love the Byakugan...but in this war it has become useless...they couldn't even scout because of white Zetsu's cloning techniques
