Depends on what your goals are. Both have strong points. Both companies make a standard chock that can be used in the pits or mounted in the trailer. They also make a trailer only version. The Condor standard, condor trailer, the Baxley LA, and Baxley LA Trailer models are adjustable if you happen to haul bikes with different types of front tires. The Baxley Sport version is not adjustable. It is made to fit a 120/70/17 tire. I like the Condor trailer mount kit better than Baxley if you remove them to use the trailer for other things or use the standard models to support the bike in the garage and pits. The Trailer Chock versions have a narrower footprint than the standard versions. The Condor trailer version is the cheapest at about $165 shipped.
I've have seen a few copies or other variations of that were just Junk
