Lately Ive been evolving my Nidorino into Nidoking at level 16, for the stats and most of the moves I let it keep it learns once its Nidoking anyway, all other moves I teach it through TM's.
My last Nidoking evolved at level 16,when it was done its moveset was Earthquake,Thrash,Mega Horn and Brick Break. I usually equipped it with a confusion cure berry or a quickclaw to catch physics by surprize for the megahorn, but hey its your call as usual in the end right?
Until Next Time..
