KDE for its Wayland performance and features and occasionally I switch to hyprland if I need a more focused work environment.
In the past I used Cinnamon but it became ever more buggier on Arch and due to lack of Wayland support still it was a dead end anyway.
I see no one has mentioned Bedrock Linux yet. Not sure though how others would rate its ‘obscurity’ though. It’s definitely a standout among distros.
