I never thought about it before but I use upstream and downstream without much though. For my personal devices and containers I use Fedora but when it comes to servers and VMs I use Debian for its stable nature.
I also run Linux mint in my homelab with pcie pass though so it functions like a normal desktop.
I use arch for all of that I’m running vms and host ssh servers also run containers & it never broken for me and to be honest your situation is weird 3 distro for one job.
I wouldn’t put Arch in anything production as it is quite unstable.
