and the all mighty three dotted sharingan and the the weak byakugan. we have no clue of wut will be the result when these two collide, since it has never been happened before. it's been said, and we saw that 3 doted sharingan can predict the next move, and it has also been said and we saw that byakugan can see the chakra movements.
since one need chakra to move any part of the body (in naruto world) wouldn't u think that neji could react much faster to sasuke's incoming attacks then the 3 dotted sharingan? or cancel each other out? now don't give me bull and try to come up with something good.
