I am honestly not sure as to what the benefit of that is compared to the approach of CalyxOS with MicroG. It has worked for me perfectly, except for one app, BeReal for some reason gives a pop-up telling that Google Play Services is missing, even though I already have MicroG fully setup and working. Other apps have all worked fine, including Google Apps like YouTube and my banking app.

I can’t confirm that (I distro hopped to NixOS) I can confirm that Arch is a solid distro worth learning and will give you the skills to manage it long-term. Compared to Arch based distros like Manjaro, EndeavorOS and Garuda where people tend to screw up their install easily when installing the wrong packages from the AUR and updating with dependency conflicts.

Mine already runs CalyOS so there’s that.
