how do these compare to the Superlift Adjustable Control Arms?

I'm running the 4" kit with only the Front Lower Rockrunner atm but planned on getting the rest.

The JKS arms use rubber bushings which I feel are far superior to the urethane bushings Superlift uses. On average rubber bushings tend to last longer, are softer, and are much quieter than urethane bushings. They don't require grease either (only the threads on the JKS arms require grease).

Aside from that both arms use a swivel in the center, but JKS uses an internal brass bearing to take load off the threads, they use a fine thread pitch (not sure what Superlift uses), and they use a crankshaft type seal to keep moisture and debris away from the threads.

I think they're much better quality than the Superlift arms personally.
