I have used most on that list and Stillwater is my favorite.. Gary's collars (which I would rate #2) are very durable, will probably last longer than the dog wearing it, but they can be hard to work with due to the their stiffness. That gets aggravating when removing a hound from its chain daily for work.. Stillwater has proven to be extremely durable on a chain as well, but is easier to buckle and unbuckle than GH's collars. Stillwater's quality and great service puts them at the top of the list for me.
