100% Agree here, although I think your point about Nagato's chibaku tensei is arguable. I give credit to Nagato the fact that he was weakened after shinra tensei'ing an entire village + he stated he could have made it bigger. I wouldn't consider Uchiha chakra a boost because the Uchiha chakra if anything allows him to manifest Madara's MS techs (Susano'o and Tsukuyomi). The reason Madara gave Nagato rinnegan was because he was Uzumaki he'd have the best control.
Anyway, the chibaku tensei as Nagato said is nothing compareable to the moon.
Uchiha chakra gives much more powerful chakra.
Senju chakra is self explanatory.
A piece of Gedo chakra allowed obito to punch through a massive boulder that previously shattered his arm.
SM allowed naruto to toss a rhino into the stratosphere.
Off all those boosts, creating the moon isn't that impressive when you take into account the moon (circumference) is only about 3x the size of the U.S - diameter the size of the US.
While coughing up blood(dying), with almost no reserves left, while funneling his chakra through only one of the 6th path(1/7 of his power), while the 6path techs are far weaker than when he uses it in his own body, nagato created a chibaku that was probably the size of konoha. That's impressive as hell right there for just a normal guy with special eyes...
How about you stop overrating Edo Madara? You don't know what powers Hagoromo did have or not,
Actually, we know for a fact he didn't have S/t jutsu, Shadow clones, Edo tensei, izanagi, izanami or shit load of current techniques which were
recently developed.
