I’d say it really depends on the packages that you use. Do you use packages that are mainly only available in AUR? I use Hyprland and thankfully TW is officially supported unlike Fedora.

I used Endeavour, but hopped to openSUSE Tumbleweed and I am currently very happy with it!

Curious, why did you decide to switch from Fold 3 to Pixel 7a?

Fellow Pixel 6a user here (with Graphene OS)! My gripes are mainly the ‘rainbow effect’ of the screen and the fingerprint sensor that doesn’t work 10% of the time.
