Updates inevitably lead to things breaking sometimes. If you want to avoid things breaking as often, using something stable (like Debian) would help.

The benefits you are describing are probably because of KDE vs Gnome and not a distro thing.

Fedora does things differently than Ubuntu/Debian (mainly package management, but there are other small things). Because of this, noobs & intermediate users alike will get frustrated at things “not being how they are supposed to be”
All that said, if Fedora works for you, keep on using it. I daily drove it for about a year before switching to other things.
Immutable distro…yeah I’m good.
