hagomoro gave sasuke and naruto equal chakra and abilities as he didn't want a repeat of his past mistake. He felt that if he left everything to Naruto his powers and abilities then the same would happen as it did with Indra. Indra got pissed as hagomoro made Asura his successor and gave his six path powers to Asura alone.

Hagomoro's philosophy of not giving a single individual complete power was after he saw his two sons battle it out for his legacy. There is no indication given that Asura was given only a part of hagomoro abilities. If hagomoro didn't care about Indra and made Asura his successor ,then he obviously would have given him his complete six path chakra( which could have given him a spsm ).

Otsutsuki's are aliens with no relationship to humans. Only hagomoro was a cross of alien and human. You cannot compare otsutsuki physiology and abilities to that of humans. They have rinnegan on their hands and only urashiki has a rinnegan in his left eye. At least for hagomoro and his transmigrants, for them to achieve the rinnegan ,they need to have a base sharingan. For an uchiha to awaken the rinnegan he needs to have indra's chakra and a sharingan. There has been no person on Naruto earth who awakened a rinnegan without a sharingan.
