If you're talking about the friction pad anti-sway device there is no comparison.
In my small mind those can't control the sway until it starts. This new system doesn't let it happen in the first place. My TV is a four door pickup,short bed. My camper loaded is near 7500 lbs. And 33 ft. I've done a lot of test driving as you can could guess. I've been camping twice. Around nine hours trip time. It is not influenced by truck traffic at all. If I new how to check the wind conditions for last Sunday, southern Indiana, I would but I bet near 25 mph. gusts.
