Naruto got no results done. Besides take down Fodder Zetsu, but everyone was doing that. And the 3rd Raikage.
Sasuke was not even apart of the war at the time did more useful stuff than Naruto:
- Like help take down Kabuto.
- Stop the Edo Tensei.
- Revive Orochimaru
* which helped save the 5 Kage.
* Reanimate the 4 Hokage.
- Manage to inflict pain to the Juubi.
Sasuke got result done. Real result, something that matter. He will be known as Sasuke The Hero of the 4th Great Ninja War.
Side Note: All other wars went on for years, Sasuke ends a war in one night. Tell me Sasuke isn't the greatest.
