Juubi madara vs adult sasuke, Kaguya is stronger than madara. Momoshiki is stronger than kaguya. Kaguya was absolutely terrified of momoshiki. She wanted nothing to do with him, she wanted an army of white zestu to fight him for her. But adult sasuke and naruto severely weakened destroyed him. Naruto had a huge portion of the ninetails taken out of him before their fight and sasuke already teleported multiple times. They both were extremely low on chakra and beat the guy who put fear in the heart of the woman who has way more chakra than juubi madara. Either sasuke or naruto at full strength could’ve beat momoshiki, Kaguya, or juubi madara.
