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.

jiraiya was only killed because he din't know pain's secret. pain acknowledges this. orochimaru was only killed because of his near death state. itachi too acknowledges jiraiya power. both jiraiya and orochimaru are sages. tsunade was able to defeat orochimaru while jiraiya was weakened by her poison.
