Tubeless tires that unseat at low/no pressure are a pain in the ass, but they're (thankfully) rare. On my wheels, one of my favorite tires will unseat, so I don't buy them anymore - there are enough great tubeless options out there that it's just not worth the hassle.
As for you, do you experience enough punctures to make tubeless worthwhile? If not, don't bother and just go back to tubes.
