I’m really liking the 28mm Hutchinson Sector tubeless tyres at the moment. I completed a Land’s End to John O’Groats ride on them recently (end to end across Britain - 980 miles in 9 days) and they were faultless. They have great grip, they are pretty fast and are pretty resilient. They’re not quite as fast as Schwalbe Pro Ones or Hutchinson Fusion 5s, but they’re damn close and can deal with bad road surfaces much better.
Another plus, although I guess this is more a function of the rim-tyre combination than just the tyre, is that they set up really easily tubeless (I can get them seated on my Stan’s Avion rims with just a track pump) and they are easy to get off the rim if you do puncture and have to stick a tube in
