Tubeless has been a topic here for 20 years or so. Over those years, the proportion of posters who tried tubeless and were dissatisfied, including those who ride upwards of 10,000 miles a year or more, seems to have been about 1%. The vast majority have been very happy with tubeless, with most saying that they wouldn't go back.

All my bikes are old enough to have come stock with wheels with tubes, and those wheels are still in good condition, so I'll stick with tubed tires. I recognize the advantages of tubeless, but I'm both lazy and frugal enough to choose to put up with fixing the occasional flat out on the road versus going to the trouble and expense of switching.

And, of course, the increased use of wider tires at lower pressure (the bike I ride most often has 38-mm-wide tires, which I maintain at around 50 psi) has reduced the incidence of flatting for me and many others, regardless of whether the tires are tubed or tubeless.
