i think byakugan is more dominant as it appears in every member of the hyuga clan. the sages son didn't have a rinnegan. rinnegan covers the entire eye, the son only has a spiral pattern for the pupils.
by this chapter of the manga, sakura is completely pushed aside compared to hinata. also naruto doesn't ignore hinata after invasion of pain. he goes to see the raikage right away.
sakura loves sasuke just like every other girl and is absolutely annoying at every turn. hinata cares for naruto solely for his nature rather than popularity and recognised him before most others.
lee can't use chakra, so neji can't block off his chakra points. but still i beleive neji will have the upper hand unless lee opens his inner gates, at which point he will win.
