I have only had the Reese Dual Cam...never had a non-sway WD hitch.
In my experience, it has made things very "comfortable" while towing. Seems to keep everything "in it's place".
There are many on this forum with the Reese Dual-Cam, and many with the Equal-i-zer. Both seem equally well-liked. Both have built-in anti-sway. A quick search on "WD Hitch" in the forum will result in MANY threads...
