Hagoromo is stronger, but Sasuke is still on his level, and your reasoning is terrible.
--Hagoromo possesses a superior bijuu (juubi) as opposed to sasuke only having it's fragments where kurama is still missing.
Sasuke merged ALL of the Bijuu's chakra together, so he has all of it minus the other half of Kurama, along with his half of Hagoromo's powers.
--Hagoromo posessss the yin and yang half as opposed to sasuke only having yin, meaning his chakra is a lot stronger and greater in quantity
Sasuke has half his power, now add the Juubi's chakra onto that. Sasuke is on his level. Pure nonsense to say otherwise.
--hagoromo posessss the RSM the same mode which naruto posessss and allowed him to blitz even kaguya
Ok? Don't know why you bothered to list this as a point considering RSM Naruto just got blitzed by Sasuke's Susanoo.
--hagoromo has both of the rinnegan as opposed to one
Sasuke can still access the full power with one, so no, that isn't even good reasoning.
and has mastered it to full extent unlike sasuke so it's clear as day that his visual prowess is also superior to sasuke
I can agree with that, but then again he used his Rinnegan to merge the Bijuu Chakra together and his completion of the process was on Hagoromo's skill level.
JJ Hagoromo>Rinnegan Sasuke w/Bijuu>Any other Hagoromo.
