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 do the same. Fedora on my laptop because I want a balance of stability and having the newest features. Servers run Debian, because I don’t have time to fix and update things.
