Arch, because I’ve always had a better experience with it than Ubuntu, be it server or desktop. I also daily drive it on my desktops.

It’s so much easier to setup. Only with Docker and MergerFS it’s a command and easily updatable, instead of the PPA setups or bash installs you have to do on Ubuntu. The wiki is still the best.

And it’s way easier to maintain when there’s less stuff.

I just run Arch on my server and spin up whatever docker containers I need.
