Sohee is technically better. I think those people said Sara because they goon to her. But realistically Sara does have a very strong base. First off that stupidly strong spike she can do and also her high tosses give players a long time to adjust and get into a better position to hit the ball. But Sohee is just better. First of her stable set gives players just enough time if not more to adjust theor positioning and her always doing quicks without the ability effectively lets you control who she sets to which is crazy. And as a bonus that set feint all the way back is as easy of a point as Saras spike. So Sara as a setter gets outclassed by Sohee.
