I've seen that a lot of people assume that
Theory: Magen: Gamarinshō worked on Nagato
"The mind" being the key term.
Pain has a central intelligence, one mind: Nagato.
Nagato attacked with Asura and Deva.
Jiraiya concluded that Nagato summoned more before having his mind bound.
Synopsis: Jiraiya's genjutsu did bind Nagato's mind for a time, as Nagato was speaking in the genjutsu world, but without killing Nagato's true body, it was futile. This is why Nagato felt Jiraiya could have won with knowledge.
Theory: Possible success of Tsukuyomi
Tsukuyomi targets the spirit/mind via visual image, not the body/brain.
Synopsis: Tsukuyomi drags the mind that perceives the image of the Sharingan in to the spiritual realm of Tsukuyomi, where the spirit/mind are dragged in, not body/brain, and tortured. Nagato, through Pain, could be targeted.
Conclusion
Nagato is overall stronger than Itachi but I do place them in the same Tier. Nagato is still vulnerable to genjutsu and Tsukuyomi. And even with CT Itachi has a good chance to seal him before getting trapped - double KO.
Bold part is something that needs to get work on.'Rinnegan is superior to Sharingan,therefore it is immune to Sharingan genjutsu,Jiraiya's genjutsu doesn't actually work,proof?Asura path managed to attack him.Nagato wasn't in the genjutsu.

It's implied that Jiraiya then released Nagato's trapped mind, then:Originally Posted by Databook
Inside the genjutsu world, the target is surrounded North, East, South, and West, by giant toads, imprisoning them in a barrier. The four unmoving toads won't lift the complete binding until the user gives the order. All that is left to do is to strike the finishing blow in the real world.

Similar to Magen: Gamarinshō, the mind is dragged in to a mental world.Originally Posted by Databook
Amidst the insight and hypnosis possessed by Sharingan, is a supreme genjutsu, born from the aforementioned hypnosis: Tsukuyomi. Originally, people on the face of the Earth live bound by limitations like time, gravity, and space; and how people exert their abilities within those restrictions is what separates the victors from the vanquished. But in the mental world where the caster drags their opponent, the Tsukuyomi jutsu gives them control over those very limitations!

Tsukuyomi's current hype as the ultimate eye technique makes it possible.Originally Posted by Databook
Sharingan is the Kekkei Genkai of the clan labelled as the most powerful, the Uchiha clan. Even among those who have Sharingan, that jutsu cannot be operated without having Mangekyou, which is its culminating point. Concurrently, the only ones who can defeat Tsukuyomi are Sharingan possessors... And even then, exclusively the elite shinobi who have reached particularly high degrees of skillfulness. Once could say this is truly a God-given jutsu solely allowed to those blessed with Uchiha blood and prodigious aptitudes. Captions: -An inner hell as eternal as Heaven and Earth. The grip held onto the principles of all creation thoroughly annihilates one's heart and soul!! -The ultimate doujutsu made possible only by Mangekyou Sharingan.
