The issue with Debian is how old application packages are, and I'm not really into Flatpak. Fedora's packages are pretty close in recency to what's shipping on other platforms.
It makes perfect sense to me that you’d feel that Fedora struck a better balance for you.
Many people prefer Debian based distros. Some people use Debian on the desktop because they prefer less frequent updates (among other reasons).
I’m just stating the obvious here, really.
