Technically speaking, it would be difficult to judge this without seeing both systems and making measurements of the actual forces.

All sway control systems work by apply force that prevents the trailer from pivoting about the ball.

Friction based systems use clamping force on a friction material to resist any change in trailer angle.

Non-friction systems use camber angles in the WD bars to apply a force to keep the trailer straight.

Whether the friction force is higher or not would of course depend on the setup and design.

(FWIW - on my 2 data points, which are different trailers, the SwayPro hitch performed much better than friction sway control on my old hitch. And this trailer is bigger and heavier than my old trailer...)

Thanks for all the great tips pulled a few more times since and seem to have found the "sweet spot" in tightening it.Thanks

Yes, too many variables to say that friction sway control will always provide more friction than any integrated system. Friction sway controller is a strong clamp for sure, with friction material on both sides of a large surface-area bar. But most integrated systems have smaller friction points at multiple points, at both ends of both bars.

I used to tow a large popup with minivans. Used a 400 lbs rated Single Bar WDH, plus a friction sway controller. Lots of others with similar setups liked the "mini-350" WDH, which had integrated sway control. I never switched, because what I had already worked so well. But when I went to a larger vehicle and camper, and needed to get a new WDH anyway, it only made sense to go straight to something with integrated sway control. Works as a system, takes less time to set up, etc, etc.

Indeed they are. The Hensley and ProPride hitches do not use friction sway control because the design prevents sway from occurring.
