Naruto got chakra from all of the bijuu and triggered six paths chakra (as a result of six paths senjutsu like Obito and Madara). Sasuke got Hashirama's cells from Kabuto (and was an Indra reincarnation) so he triggered six paths chakra that way. Hagormo's benefit is arguable. Some say he only gave them the seals on their hands, sun and moon.

I believe that Hagoromo gave the boys the sun and moon seal, as well as SPSM to Naruto and Sasuke's tomoe rinnegan that allowed him to retain his EMS powers in his rinnegan. In the end he only took away the seals.

But in the end, both Naruto and Sasuke awakened/would've awaken six paths chakra without Hagormo, because of the reasons from above.
