Signal is an interesting case study in UX failure. I and a bunch of other tech forward people were on it in its heyday but after they removed SMS support and implemented shitty UX like that nag dialog: Neither I nor a single person I know uses it any more. Everyone is on Whatsapp or iMessage. It may be cryptographically superior, but does that matter at the end of the day if nobody uses it?
Cryptographical superiority aside, Signal doesn't collect personal data, unlike Whatsapp. For me that's the main reason to use it. The UX is good enough, although some points can for sure be improved.
