I have all 3 tracks on sleds, 3” PC, 3” alpha and 2.75 polaris. For a deep powder track the alpha 3” really is king, the doo 3” is pretty close (yea, have one of those too). Personally I think the 2023 new doo 3” will reign, but it’s untested yet. Also hard to compare the 3” cat track to the polaris 2.75. In my experience the 2.75 trenches less than the cat 3” track, simply because it doesn’t have as much lug. It also doesn’t propel you forward as quickly as the cat 3”, for the same reason, less lug height=less traction in deep snow.
IMO, all three manufacturers are making very good factory tracks. Each has its own characteristics that make it slightly better in various snow conditions. I did punch and clip an alpha 3” for a twin rail snd it’s my favorite deep snow for sure on a non alpha sled, doo 3” is a very close second, but has to be cut down to 15” wide
