Ubuntu Touch has amazing UX, IMO. Sadly it's been non-viable for practically forever, and is non-viable today unless you want to use a 7-year-old out-of-production device. It's practically abandonware with a few hobby maintainers at this point, as much as it had potential compared to other alternatives.
I was under the impression that Ubuntu Touch worked just fine with the Fairphone 5 which is very much not a "7-year-old out-of-production device". I'm currently writing this from a Fairphone 4 (with CalyxOS, not Ubuntu Touch though).
