Kishimoto wasnt super clear that the Rinnegan being a Sharingan evolution was just a misconception by Kabuto/Orochimaru, so fans think it has all the perks of a Sharingan/Mangekyou Sharingan. We know this isnt true because Madara had to deactivate the Rinnegan and use the Mangekyou Sharingan to cast a genjutsu on A.

Sasukenis the only Rinnegan user shown to use MS abilities and he got special mods from Hagoromo

I see.

I think he's referring to Itachi's Mangekyou Sharingan overpowering a 3TS user. Who, unknowing of Itachi's MS or level of power, tried to place him under Genjutsu to immobilize him. But Itachi's reflexes were so sharp, that he countered. Tekka Uchiha being the victim from the novel.
