Now that you mention, only stomping the zetsu clones wasn't everything Naruto did. He was maintaining the clones on every field along with fighting Edo Jinchuurikis. And talking about Nagato, in one way or the other Naruto could have managed to fight back with medium to high difficulty because he already faced him in the village. Also his clone nullified Madara's Mokuton Jutsu. Also Naruto didn't asked Itachi for his help to stop Edo Tensei
But Sasuke, pulled a susano'o to stomp some Zetsu clones. Naruto had a purpose in using the Kyuubi Chakra mode in the war. Also Itachi didn't asked help from Sasuke to capture Kabuto. Sasuke was doing nothing while aiding Itachi apart from spamming Amaterasu. Itachi did his job by capturing Kabuto in Izanami.
No matter how you cut it. Naruto (for now) is above Sasuke.
I know that Naruto is above Sasuke for now.
For Naruto :
Against Muu , without Gaara and Onoki , he wouldn't have done it.
Against 3rd Raikage , without Rubber dude , the division and Hachibi , he wouldn't have done it.
Same goes against Madara.
And against Zetsu he used KCM too.
Sasuke also was testing his eyes against Zetsu and don't forget that he killed the original one.
And i'm sorry , but without Itachi , he and Bee would have been dead.
Same goes to Sasuke against Kabuto.
And also Sasuke saved Itachi twice against Kabuto , and used Amaterasu twice ( so not spam here ) , so he didn't stand there doing nothing like you said.
