I don't think so, I use both Ubuntu and NixOS every day, and split my extra-curricular activities between the two communities.

I've got a couple of actual machines running Ubuntu, and run it a lot in VMs/LXD containers depending on what I'm doing (see: https://jnsgr.uk/2024/06/desktop-vms-lxd-multipass/).

On my personal machines I'm running NixOS because I find it interesting.
