i've not seen those BlueOx anti sway bars before, they look pretty cool, the WDH capabilities of the cheap flatbar WDH I used years ago, with the antisway built into the pivots for the two spring arms.
I like the Andersen because its easy to hitch and unhitch, you lift the trailer weight off the ball, loosen the nuts and the center plate comes free, then finish jacking and unhitching. to hitch, you drop the hitch over the ball, put the plate back under the hitch on with its pin, then drop it the rest of the way, and crank down on the two nuts. I carry a cheap 3/8" ratchet with their aluminum socket, and the weight distribution on my setup is just about right when I have it 'damn tight' on each side. Sure, the friction element on the hitch shaft wears out, but that is a $18 plastic cone and maybe a $69 tapered ball, and easy to R&R.
I'm towing a 2014 E21 with bikes on the back thats probably near weight capacity behind a 2019 Ford Expedition Limited 4x4. This Expedition is a standard, not long wheelbase (aka Max or EL), and it has the CCD computer controlled shocks. We made it 9000 miles through Mexico with a plain hitch, but when we got back, I went and bought the Andersen, it completely controls any tendency to sway, and has just enough WDH to keep the Expedition riding level and not bobbing. With a bigger wrench, I could get significantly more weight distribution.
I used to tow this E21 behind a 2002 F250 diesel 4x4 longbed... didn't need anything to be rock stable, really couldn't tell the Escape was back there. heh.
Before that I towed a Casita with a Tacoma 4x4... I got a classic chain bar style WDH to control bobbing on bumps, I used it for a year... but then I put airbags and bilsteins on the Taco, and didn't need the WDH again, it drove just fine.
