Itachi:
-dealt with all of Nagato's summons.
-figured out a way to counter Nagato's strongest move.
-burned Nagato to a crisp, chopped his arm off, and then delivered the final blow with Totsuka.
If you ask me, the entire fight was just a subliminal Itachi wankfest.
-When Kabuto was focused on Naruto and Bee.
-That doesn't mean he would have figured out all of Nagato's secrets since he didn't really fight Nagato.
-Nagato sensed Amaterasu but KA freed Itachi then Itachi used Amaterasu on Nagato Summons and Nagato. Itachi only was able to cut off Nagato's hand because Kabuto was focused on Naruto and Bee. No knowledge of Totsuka blade, Nagato is cripple and plot stopped him from ST the blade away.
There is nothing nagato can do to save summons from amaterasu unless run to burning area and preta absorb it, kinda hard with his mobility. Finding blind spots for MS user like itachi is piece of cake, his shuriken just take 1 second.
Kabuto did all he could do with nagato, there isnt anything better that nagato himself ever displayed. Its just general speculation that nagato would do better on his own. Nagato got power, kabuto is intelligent as hell and better at using nagato's power. Itachi was edo as well? Your point?
Naruto can move the flames off his summons as he lifted the nail from the piece of wood

. Nagato can control 6 bodies at once, Kabuto didn't do this. Nagato more than likely would use a summon to for mobility, find some ninjas, kill them and use their corps. Nagato also mastered all 6 elements at a young age yet haven't shown to use any of them.
Itachi benefits from being an edo even though he wasn't at full power, he no longer had his disease which he was dying from alive so he could go all out, he didn't have to worry about his low stamina, didn't have to worry about the pain that he feels when using his MS jutsu and Susanoo was the worst of it.
Rinnegan user has better vision than MS since it's a more evolved version and Nagato had it far longer than Itachi had his Sharingan. He's higher up than a Senju or Uchiha, he's a path of the Sage just like Madara and Obito.
Nagato would fight better with his own free will? When was the last fight he himself has fought? Deidara sucked. Kabuto took on other's powers and went against uchiha bros. Saying he sucks using others is false.
Lol show me a scan where one can sense chakra less items such as shurikens.
Its impossible to time shinra tensei with amaterasu. Amaterasu appears on target, ST wouldnt blow it off from summons and even if it did it would own the summons.
Nagato in his own free will would make use of the 6POP unlike Kabuto, even Obito made use of it with the Jinchuurikis. In a one on one fight with alive Itachi, what does Itachi do when Nagato use Deva path ability to push him miles away? This alone was enough to push 3 Giant toads and broke all of Gamabuta's bones. Then have his bird fly him over Itachi and shoot missiles while the bird drops it's exploding eggs down on Itachi while sending his invisible Lizard (he'll have to active the sharingan's chakra seeing ability which is not always active) at the same time.
Shurikens would get evaded since Nagato would see them, it would simply me like what happened with Jiraiya

. Sensing Amaterasu would allow Nagato to either push Itachi with Deva before he use it, attack Itachi with his crab stream of bubbles

which would take Amaterasu like Sasuke's Katon did
