I'm using e.foundation for a while now on my Moto G3 (osprey) and it's working ok despite a few camera/gallery crashes here and there.
The only thing I'm not really fond of, is that the apps come from an opaque source (https://info.cleanapk.org/). I also found no information on how those apps are signed, and how this is checked. Upon asking them, someone pointed me to a git commit where an outdated public key of F-Droid was used.
