I think only the Snapdragon SoC is fully supported. So, yes, the google Pixel phones and the Xiaomi Mi A2 are curently recommended: https://calyxos.org/get/
I've flashed mine 2 weeks ago and I am very pleased. Without the Google Services Framework you are restricted to the F-Droid store though (not a problem for me personally). And there are several Apps that won't work even if you install the GSF and the Aurora-Store: Banking-Apps, Online-Check-In for Flights, etc. -- again not a problem for me personally, I fly maybe once every 5 years and use Online-Banking from my browser...
