I’ve settled on Ubuntu in 2008, but jumped between Gnome, KDE, Unity and LXDE. Then I got a Steam Deck last year and it became my main machine, so now I am not only with its Arch based OS, but I a secondary Arch SD card that I occasionally boot, if I need something not immediately available in SteamOS.
Servers? Debian Since 2019.
I’ve been using it for many years with my four mailboxes and I am very happy with it!
