Nice! I started using it just this week. I built a computer to serve as NAS with Debian and ZFS.
I'm also considering moving my Ubuntu based server to Debian; it gets too many package updates that I frankly don't care about, plus even Ubuntu server feels a bit bloated.
I moved from Gentoo to Ubuntu a few years ago precisely to reduce my workload; I just wanted it to work... and now I'm considering Debian for the same reason.
I'm in a similar boat. I've been using Ubuntu on my servers for years but all the crap around snaps and paid sec updates has worn me down. I'm actively in the process of switching it all to Debian.
Snaps seemed like such a time-saver until I tried installing some and they just didn’t work at all, or needed some workarounds and janky weird solutions to even function.
Specifically I’m talking about microk8s. What a god-awful snap, I never got it working and it’s completely broken out of the box. Ugh, I’m eyeballing a move to Debian for my headless servers too.
Something a Gentoo user might care about is the distro's compile time options. Ubuntu uses -O2 and LTO, Debian uses -O1. Debian has always been noticably slower overall for me.
Don't do what I did and go with Tumbleweed. It gets more updates than Arch.
