I think its much more about the better heat dissapation under repeated use, and less distoration when really hot. Also some people panic when drum brakes start to fade - because all the mechanical adventage of the self-engerizing fades away with it. Not to say their aren't crappy OEM front disc systems. Many a first gen SHO owner found that out. And there are some Subies that even in autocross seem a bit undersize in the front brakes.
