Madara and Sasuke's eyes don't have the same ability.
Sasuke and Kaguya's eyes don't have the same ability.
Hagoromo doesn't get Madara and Sasuke's Limbo and S/T Ninjutsu.
Wrong buddy. Get me panels of him using her jutsu, or anything that states he can and then I'll concede this point.
She has the Rinnegan, which lets you see Limbo. Lol.
That is exactly what it means. Sasuke attacked Madara with S/T and tagged him, Kaguya was attacked and she FLEW OUT OF THE WAY. The one who dodged is the faster one. That simple.
Juubi Chakra Arms got slapped away by Yin and Yang Kurama Avatars. Kaguya's smashed PS open. No comparison. Kaguya's Gudo Dama is also much stronger than the ones on Madara's back, so there is no comparison there either. Not to mention Gai was smashing shields made from them, Kaguya manhandles it.

Susanoo is Ninjutsu.
Kaguya has the Rinnegan, has the power of the Sharingan and she has all 9 Bijuu + chakra that she got from the fruit. And lol, Sharingan can't copy KKG unless you have that KKG already. Madara doesn't have Kaguya's bone KKG so he can't copy it. Nature Manipulation can't be copied either as it uses no hand signs. Same with the bone KKG.
