Sasuke does not have the reserves to spam the Six Paths techs like Nagato did. As Obito who had half of a Hashirama clone/zetsu body on him could only handle one eye and could not spam Six Paths techs. Nagato was a Senju/Uzumaki so he had the best body and reserves one who is not an Otsutsuki could get. He could even use and handle the Rinnegan before he was even a Ninja, he mastered all elements at age 10 with it, and he was learning and developing ninjutsu all the time with it such as Rain Tiger at Will technique. Nagato was simply a unique case. Sasuke just doesn't have the reserves for it.
