Dual cam VS Equalizer...I have both

The sway-control effectiveness is determined almost entirely by the base force applied to the WD bars. `The additional force due to lifting of the bar by the cam and due to differences in bar stiffness is negligible.
IOW, friction has everything to do with it.

This post was a great explanation. Thank you for the education. Also, relative to the quoted portion of the post, Reese makes a round bar WDH and if you read the directions, to install it correctly, the bars are to be parallel to the trailer frame. Reese never makes a claim that their trunion bar setup provides more sway control than their round bar setup.
