Else, Sasuke's dojutsu make no sense in the Naruto Gaiden manga. After all, that Gaiden shows clearly that his MS powers are linked to the Tomoe, without which he cannot use amaterasu/susanoo. Clearly, the Tomoe in the Rinne Sharingan refer to the Sharingan, whereas the ripples refer to the Rinnegan.

Besides, it's evident that the Rinnegan doesn't have the same predictive capabilities as the Sharingan, nor its illusion abilities.
