Nobody informed will follow Sasuke. However, in the panels where he is trying to basically execute the Juubi, Alliance soldiers are cheering on Sasuke, so not everyone will know I'm guessing nor will they understand Naruto's preservation of the Bijuu when it comes to it I am guessing.
He is a powerhouse, and many will probably see him as the man who tried to execute both the Juubi and Obito, as opposed to Naruto's "peacemaking." Some may sympathize more with him, especially considering how influential he was in the battles.
I think he would get a decent following in this scenario assuming not everyone (mostly unnamed characters) are aware of his past involvements, however, he will have Taka, Orochimaru, and Kabuto instead of Kages and Leaf characters.
