beh.. so easy, vote for sasuke-rinnegan of course!

hmm, by lore i'd rather say that the uchiha could have manifest senjutsu into the sharingan

however only after mastering the etermal mangekyou sharingan > thus helping awaken the rinnegan

whereas, the senju's mastering of senjutsu is on it's own an entire wholesome realm not just in the eye's jutsu.

debate-able perhaps ?
