I had the E-Qual-i-zer which is a good sway control WD hitch, the sway control is controlled through steel to steel friction. After a white knuckle experience I researched, purchased and installed the ProPride 3P hitch which is the next generation Hensley as in Hensley Arrow and actually eliminates sway rather than just control it. It is like night and day difference, the trailer tracks like it is on rails and I no longer feel the big rigs passing or me passing them like I did with the E-Qual-i-zer. Some will say you don't need to spend the amount for the ProPride or Hensley, but to me, just one white knuckle experience avoided which could lead to a deadly situation, is worth every penny for the added safety of my precious cargo!
