I have /e/os. I decided on that pretty early on in my degoogling journey. Main reason being that I believe any privacy venture will come with tradeoffs, but I went with the "most things will work" approach. They have this neat privacy manager that tells you which trackers come from where, and I think that covers my needs. There has been exactly zero apps that haven't worked so far, and most people that use my phone just think it's a standard pixel.

The app lounge kind of blows though. I use the F-Droid app for updating F-Droid apps instead of it, since there was some weird stuff about where they were getting open source apps from. I use it for the play store, and it does what it needs to, although there is some weirdness with it like not being able to tell which apps have recently updated and when. I like the idea of joining app repositories together, but it needs work.
