I'm going to throw my support behind this one as well. I'm circling back to Debian after a long stint on Fedora on my primary machine. I've been running Debian 12 on my desktop for several weeks now and it's been pretty great.
it is one version behind fedora in gnome releases, so I installed the latest gnome from the experimental repos and that worked pretty well. I don't know if I would recommend that for anyone else, but it worked for me.
I have a few personal servers still running CentOS 7, but I will be migrating them to Debian slowly over the next few months. I suspect I will go fine. Debian organization to maintain FOSS ideals over the next 5 to 10 years, so it seems like a good default for me.
I have read about Vanilla OS. It is Debian based with some neat features stacked on top that might be fun for a desktop OS. I can see myself switching to that on the desktop if they deliver on all their promises.
