Granted these alternatives DO do great in Superfly. But you can't texture a truly rough surface where you see the edges with it. Edges look smooth as glass. The only real reason in my estimation to have displacement is to avoid that edge smoothness. Don't get me wrong I love Superfly, this is the one thing that bugs me. (that and shadow catching ... and that too is being implemented within the next few months to the original Cycles at the Blender Foundation)
