If your argument is that the Rinnegan is more advanced than the Sharingan, I have a counter. My logic is that the Sharingan can perform techniques the Rinnegan can't (Amaterasu, Tsukuyomi) despite the fact that it's a devolved form of the Rinnegan. So just being a Rinnegan doesn't make it automatically immune to the Sharingan techniques like Tsukuyomi, because the Sharingan developed in a different direction than the Rinnegan.

The two are seperate dojutsu at this point; it's not as easy as "The Rinnegan is the advanced form of the Sharingan. Even though the Rinnegan is more powerful overall, the Sharingan has abilities the Rinnegan doesn't have. So naturally the Rinnegan shouldn't be an automatic counter to the Sharingan. My main argument is that the Rinnegan is capable of dispelling the Infinite Tsukuyomi alongside the chakra of all of the tailed beasts, and it is capable of defending from it with the assistance of susanoo. If it is powerful enough to counter and dispel a jutsu of that caliber from a higher dojutsu (Rinne Sharingan), why would jutsu that are significantly weaker (Tsukuyomi, Genjutsu:Sharingan) and from a lesser dojutsu (Sharingan) have any effect on it? Neither Kakashi nor Itachi bothered to use genjutsu on Pain and Nagato either when it would have been very helpful, especially in Itachi's case (since he's a genjutsu specialist), which makes it easy to assume that they figured it would have been ineffective especially considering how intelligent those two are.

@QuakingStar Obito barely utilized his Rinnegan though tbh, so it's likely that they had a battle between their Sharingans considering Obito casted genjutsu as well during that fight.
