Madara had his 2 Rinnegan back. Doubt Sasuke and Naruto can stand a chance, especially in a Taijutsu battle.His feats are how he went toe to toe with two individuals who would wreck both JJ maddy and Kaguya in a pure taijutsu match up. Put JJ maddy or Kaguya in the same situation they would lose much worse. Narusasuke would throw them like a rag doll. Any Jutsu they use MomoKinshiki would absorb. His eye didn't change color for show. They actually got stronger.
And Sasuke is a special case he is the ONLY person with one Rinnegan he doesn't need two. The tomoe must account for that. Also, Kaguya doesn't have Rinnegan that is a Sharingan.
