sasuke developed the sharingan at 12... which is kinda late i think for an uchiha genious but he learned super fast taijutsu in 1 month..

neji learned kaiten on his own and the hakke move... and best of the hyuga..

i know itachi was some kind of ultra genious and they can't compare to him but i want to know who do u think is more of a genious sasuke or neji
