I bought a BAL (tripod) stabilizer a few years ago and use it at almost every camp site; if the ground is generally soft, it is usually not worthwhile. For that reason, I wish it had larger "feet", but that would make the folded unit larger. I occasionally place wooden or composite blocks beneath them for added stability (and less "sinkage") as necessary... compromises.
The tripod, when properly installed and used, will reduce the amount of RV movement, most noticeably in the front area of the interior. There is likely no device that will eliminate all such movement, but walking without stomping is helpful.
Another advantage is the tripod legs serve as a warning to not bump into the leading edge of the pin box, while still leaving sufficient space beneath the overhang to store stuff and possibly (but carefully) walk beneath.
Again, there is no "best" (other than counting the votes), but there are some things that may help.
