I haven’t used the UST wheels as they seemed to be specific to certain tires but I’ve been using tubeless since 2013 and exclusively for the last 3 years or so and won’t go back. Both the Reynolds and November wheels are tubeless compatible. Just do a search on my opinions on tubeless but I’ve used quite a few wheel and tire combos and enjoy them all (my vice seems to be buying and trying new wheel/tire combos).
i have never had a challenge dealing with tire installation with the exception of my current continental gp5000’s which were a bear to get on although I’m told this is the same with their clinchers. Still, once you get the method it’s not too bad!
