I used it for years, owning multiple phones, up to 1-2 years ago, then switched to Graphene OS and never looked back. It is an interesting project, with a very innovative UI and very close to a true GNU/Linux on your phone. But ultimately the reasons that led me to change were: (1) they never managed to get the critical mass needed to continue, so there were very few native apps that were more than hobby projects (2) the Android support was never 100% working and stable for me, with frequent connection drops in particular and some unsupported apps (3) a small team meant that both Android and Linux security patches were always months behind upstream (4) it's not really open source in the end.

But mostly it was (2): on my daily driver phone I need to be connected 100% of the time, things like the Android networking silently failing were a major problem.
