However, it seems that the Otsutsuki have been busy murdering the heck out of each other, e.g. the ones on the Moon.

Hence Kaguya is stronger than Momoshiki I don't disagree with this, but there are two important notes to make here:
 * That Momoshiki is likely a descendant of whoever Kaguya truly feared. It's possible that this person was stronger. It's also possible that the fruit from which Momoshiki and Kinshiki got their powers, was divided among a greater number of Otsutsuki and segments of it's powers were lost.


 * that Momoshiki's ability to absorb ninjutsu is actually very problematic for Kaguya considering her immense reliance on ninjutsu. Taijutsu is the main weakness of Momoshiki, which Kaguya barely does.

Considering what i wrote above, it's also likely that her eating of the chakra fruit went against the established laws (turning it into edibles and sharing the power), so it's likely she had to defend herself against all other Otsutsuki involved with this shinju plan.
