- Desktop: Manjaro Gnome, for that amazing macOS-like desktop. It even does the 3 finger swipe up to see all your apps with Apple's Touchpad.
- Phone: OnePlus 8T with microG variant of LineageOS (alternatives: Pixel line-up), because that allows me to still receive push notifications. I have over 40 apps and only found 1 that didn't work so far (which is Uber Eats, because they seem to require Google Advertisement ID). I pushed a modified Google Camera app to it, so my camera is better supported. I think only 3 out of 4 cameras are working, but I don't care.
- Watch: Amazfit GTR 2e with the official app. Alternatively it should work with Gadgetbridge if you don't want to use the offical app ("Zepp"). Amazfit GTR 2 is a better option if you want it to have WiFi and want to store music on it.
I may just go LineageOS.
The big advantage to CalyxOS or GrapheneOS versus Lineage is they support re-locking the bootloader, which means that verified boot still works - important if your phone gets swiped.
Many apps are also compatible with GrapheneOS and installing https://grapheneos.org/usage#sandboxed-play-services provides broader app compatibility.
Not to go off topic from your main point, but what did you move to?
