LineageOS with microg. Running now since over a year. The last upgrade from 18 to 20 was a bit of a hustle, as i had to upgrade my TWRP. So far i'm quite satisfied. The only thing that bugs me is, that i cannot use paid-apps from thr google store. I don't always find an open source alternative fromF-Droidm.
I'm not sure if /e/ solves this problem i a better way. Was thinking about migrating to /e/. But, als LOS was running quite ok, i did not bother.
