You have to remember that when you actually awaken the Rinnegan in both eyes it doesn't have Sharingan abilities and you can't turn just one of the eyes into a Sharingan, MS, or EMS, Obito just transplanted one eye. Sha-Rinnegan just has the Sharingan/MS/EMS abilities combined with the Rinnegan, while the Rinnegan part itself is actually enhancing those abilities at the same time such as with Sasuke's Genjutsu power being on a new level now. It was also quite clear that each Rinnegan user has ONE technique that is unique to them, Madara had Limbo Border Jail, Sasuke has his shifting technique and Kaguya had her dimension crap
