The Schwalbe One tubeless is a tire that trades everything for grip and low rolling resistance. It's like an F1 tire for a bike. If your roads are immaculate, expect around 1,200 miles from a rear. If they're real-world roads with potholes, chipseal, and the usual detritus, expect 900-1,000. There is absolutely zero flat protection built into a One, it all comes from the liquid sealant. And everything will puncture. I had to top off sealant every 2 weeks, just from the amount expelled during punctures.

But man, were they ever fast and smooth.
