Tubeless can be a pain but it is exceedingly good at dealing with the small annoying punctures. Pretty typical to not notice a puncture at all before it seals. Caveats: for some reason pinch flats in the sidewall seal poorly, and the sealant must be kept somewhat fresh.

The one time I had it fail me entirely, it was in New Mexico where the goathead thorns are relentless. I had about a dozen thorns in each tire, and my half dried up sealant was no longer up to the task. Still hard to imagine going back to tubes, even though I carry lightweight TPU tubes as backups.
