You went about this all wrong but i'll help you out. First you should have noted that Naruto was training before fighting Pain and splitted his chakra among his 2 clones that he left behind to gather natural energy. (how shadow clone work as explained when Naruto fought Neji: Naruto evenly splits his chakra among his clones).This means Naruto was barely at a 3rd of his power (strength and speed wise).
You can also bring up he fact that SM Naruto is stronger than Tsunade. Back when Naruto was fighting Pain, Shikaku (smartest guy in left village) said Naruto was on another level than anyone in the village even tho Tsunade is there. He clearly knows what Tsunade is capable of but also knows what Sage mode is capble of, probably from Jiraiya. Also note that Madara's incomplete Sasunoo is as strong as Itachi's complete Sasunoo, only because there's no way Itachi's Sasunoo is close to Madara's. Tsunade punched threw Madara's uncomplete Sasunoo.
Naruto can avoid genjutsus by closing his eyes and using his sensory abilities to see and react to any attacks. Naruto's clone was able to dodge and counter the 3rd Raikage's attack (3rd Raikage faster than Itachi).
Also don't sa anything about Itachi being smarter than Naruto because Naruto beat ninjas who are smarter than him (Neji, Garaa, Kabuto, Kakuza, Pain, pretty much all of his fights) by using his own brains and fighting style.
