Actually, both Naruto and Sasuke gained half of Hagoromo's chakra. The only difference is that Sasuke didn't have senjutsu powers and as such he gained the Rinnegan by evolving his left Sharingan; Naruto mixed the Six Paths Chakra with his senjutsu abilities to awaken the Six Paths Sage Chakra, enabling him to gain Six Paths Senjutsu, and by extension Six Paths Sage Mode. Why Naruto didn't gain the Rinnegan is a mistery. Many believe it is because he doesn't have the Sharingan.
