I have nothing to compare to, but I like mine. This being my first WD hitch I did a bunch of research and was impressed with the simplicity of this hitch and the smooth (quiet) operation. I tow a 29 footer with a Yukon XL and no real complaints so far in 2 years.
Ken, I don't have one but it has been discussed frequently on the forums. Click here for results of a search on Andersen hitch.
In a nutshell, the consensus seems to be that it works well enough controlling sway but it does not do so well with weight distribution on heavier tongue weight trailers. There is also some concern with using the hitch with certain couplers. Barney
