I daily drive Ubuntu touch on a Fairphone 5. It is totally doable, but there is some sacrifice compared to the experience on a commercial OS. I think you will also get the best experience on UT if you lurk around in the community, as there are some good tips there on how to get the most out of it. (Like which smart watches are compatible, which browser is the least buggy, how to customize stuff)
