Short version- I gave it a try, didn’t like it much, went back to standard. For me, it was bad at things that are important, and good at things that aren’t, or that normal tyres are also good at. But there’s a big ymmv in there, it depends on your riding. There’s a couple of local trails where it really was good- fast, flattish, rooty singletrack without too much mud or hard use- and if I did more riding like that, I’d like it more.
It would give you more comfort seated on a hardtail, though. But then, the extra maintenance of a full suss is way less than the cost of changing bikes
