This is a reply to both quotes: Chakra absorbtion (even through other jutsu: e.g. Six Paths of Pain) is indeed a feature of the rinnegan. Quite frankly, i think that's how Nagato planned to defeat Naruto with Chibaku tensei in the first place (way, way back).

I think it's clear that power-wise, both Naruto and Hashirama were the superior of the other. The Sharingan and related Dojutsu simply grant tools that allow the user to match or negate enemy powers. The strength of the Rinnegan is it's Utility, not the raw power.

This is why Hagoromo was basically a god: with the power lottery of the Rinnegan, the body of a Sage and the chakra of all Tailed Beasts, there's no weakness and nothing you can't do.
