The main difference is in the perspective. Regular Sasusaku fanfic will usually be about building up and exploring the relationship between Sasuke and Sakura. However, anti Sasusaku fanfic will often highlight the problems or flaws in that relationship. They might rewrite scenarios to make the relationship seem unappealing or unrealistic. For example, they could make Sasuke be really cruel to Sakura in a way that is not shown in the regular fanfic. They also might introduce new characters or plot elements that disrupt the Sasusaku relationship.
Anti Sasusaku fanfic focuses on going against the Sasusaku relationship. So, while regular Sasusaku fanfic might show the growth and love between Sasuke and Sakura, anti ones would show the opposite. For example, they could show Sasuke constantly rejecting Sakura or having a negative view of her.
Regular Sasusaku fanfic is all about celebrating the relationship between Sasuke and Sakura. It might show their journey from being friends or comrades to falling in love and building a life together. But anti Sasusaku fanfic is a different beast. It could be born out of disappointment with how the relationship was portrayed in the original work. These fanfics may go to great lengths to break down the relationship. They might show that Sasuke and Sakura are fundamentally incompatible, perhaps by emphasizing their different goals or values. They could also change the story so that other characters influence Sasuke or Sakura to move away from each other, which is a far cry from the positive portrayal in regular Sasusaku fanfic.
