They roll quick, they're light and seem to have great puncture protection on the tread surface. But the sidewalls constantly leak tubeless sealant. It then attracts a lot of dirt and grime causing unnecessary clean up. I was told it would go away after a few days but after months it hasn't stopped. I now have to top off my sealant once a month. I also had one sidewall blow out on me at the tread/sidewall seam. I am going to switch back to latex tubes to end the hassle.
