As mentioned, SOFT-T or CAT are the current gold standard. Nothing else even comes close, especially not the Chinese knockoff garbage, ive seen documented cases of those failing in real world use.
Both are great but have their differences.
CAT is easy to setup to use one handed because of a prepositioned loop,but that also means you are locked into looping around an extremity unless you unfo the velcro. The downside is that they are not as robust as the SOFT-T, and can suffer from abrasions, tears, and exposure to UV light. If you are really out and about the velcro can pick up burrs from plants, or get caked with mud making it completely slick. The windlass is attached to an extremely light ribbon to create tension which will stretch and become useless if you tighten it for training, so as mentioned get a training piece or save an old one. The CAT has a lot more aftermarket carry options as well.
SOFT-T is more of a long time use item, with a metal windlass and thicker material. The newer gens all use a metal clip to lock around the extremity, which can be pre-positioned for one hand use but you may have to cut or tape the extra tail of material. It has no velcro but also no writing surface for time like the CAT. It packs down shorter but a little fatter than the CAT. I would suggest "breaking in" the clip, and popping it in and put several times to make it easier to do, it can be a bit tight.
I use a mix of both and have had success with both. Its really just shooters preference.
