While the Reese may have a selling point that it stays in a detent position, impeding sway, the fact is that it is which is no different than a friction producing device. The disadvantage of the reese, is that because it is resistant to "give", it puts unnecessary strain on the trailer frame, and the rear end of the TV. Also causing excessive push to the TV which can make the TV lose control, especially when cornering. There are no proven studies that say one hitch prevents sway any more than any other anti sway device. However, when you look at the physics, the ease of installation and hookup, you will go with the equalizer.
