Naruto, Sasuke, Kaguya, Hagoromo, Hamura, Juubito and Madara can beat him. The rest doesn't need to bother. Sasuke cant defeat him. Kaguya embarassed his bitch ass the whole fight and Kakashi blitzed her easily with his Kamui Raikiri. Sasuke has no chance against Kamui Susanoo.

Juubito lost to pre Rikudo Naruto and Sasuke and couldnt use Kamui. hes not beating Kakashi either.

also forgot Momoshiki and Kinshiki.

So the real answer is Naruto, Juubidara, Kaguya, Hago/Hamura, and Momoshiki and Kinshiki.
