Just because Sasuke has the same eyes doesn't mean he is equal to Kaguya. Her powers came directly from the god tree by eating the fruit. She had the god tree chakra and eyes. I believe she was able to use senjutsu which is something Sasuke haven't shown us he can do. He will need to be able to use senjutsu and I think he will thanks to Juugo giving him his dna and chakra. Sasuke's senjutsu won't be as strong as Naruto's or Kaguya.
PS: Naruto has the god tree chakra through the tail beast.
Jubi power is what awaken kaguya nine tomes and causes her to be full of chakara.she's the first person to use chakara. Her real power lies in her nine tome, its her trump card base on manga. Senjutsu or "jubi body" never even mentioned related to her. So its all fair game. You might say sasuke can't use his eye like kaguya did. But if you understand what nine tomes is, it just a matter of time, especially he has the potential to awaken two(most likely)
It's just like when you compare two ems, their potential not far off, and sasuke's eyes tend to be stronger one as always(these are proven facts)
