That's why both of them are considered the threat, and after Momoshiki absorbed Kinshiki he was the fusion of them both, being the threat in one. Making him stronger than even Kaguya at that point, he may not have Kaguya's insane dimensional phasing and transitioning powers but he could still beat her in a fight. It should also be noted that when Kaguya came back to life she probably was significantly stronger than when she was alive initially because this time she was connected to every single person and their chakra in the world, while before she could only rely on her own chakra.
