I use /e/. It's a pretty good experience, a bit above LineageOS for microG.
The major downsides are a bit of a weird launcher, camera app (OpenCamera ... but worse?) and them occasionally pushing their weird services (some account and the absolutely terrible search engine). Those are all easily fixed, though. What stays is a pretty solid version of Android with almost everything working (the best experience I've had with microG), which is a pretty big achievement without Google Services (... and with Android).
You may want to install additional location (NLP) providers, my experience with the pre-installed ones was not very good. I also have occasional issues related to the camera (probably specific to my device).
A fun side-fact is that they use Bromite (great version of Chrome) as the default browser without crediting the author, just calling it "Browser". As a techie I don't like this obfuscation, but for non-techies it must be great.
