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. So say he only gave them the seals on their hands, sun and moon. But in the end, both Naruto and Sasuke awakened/would've awaken six paths chakra with Hagormo, because of the reasons from above.
