Kaguya. Kaguya is way more powerful than Madara in all areas and even though he is a more skilled fighter, he has no way of countering most of her moves. Naruto and Sasuke were overwhelming Madara in their fight the whole time and even when he got both Rinnegan and absorbed the Shinju Naruto was able to quickly counter his improved Limbo technique and Sasuke could protect them all from Infinite Tsukoyomi. Kaguya on the other hand, had chances in which she could have killed Naruto and Sasuke but instead focused on splitting them up and just absorbing their chakra.

Only at the end, when she intended to kill them by taking them to her gravity dimension and using her all-killing ash bones did she nearly kill them and Obito sacrificed himself to save them. Then they were still losing and didn't have a way to counter her Expansive Truth-Seeking Ball until OP Complete Body - Susanoo Kakashi with Kamui stepped in to assist them alongside Sakura and they defeated her by sealing her as she was truly immortal in all aspects and couldn't be taken down any other way.
