I used to prefer GNOME, until I started using KDE daily on the desktop, I thought it would just be temporary, but I ended up liking KDE way more because of the features that are built-in, the integration is simply priceless and I’m tired of those GNOME extensions that keep breaking at the next GNOME major release and I have to wait weeks for the poor devs to catch up and fix them up to get the compatibility going again, in some ways that also happens on KDE with the widgets, but, arguably, you will need way fewer of those to extend the already wide functionality provided by the Fedora KDE experience, so you risk incurring in that issue a lot less. Note I specifically mention Fedora both because it’s the system you want and because the pool of apps included is the best for a streamlined, but not bloated, experience, which also allows me to use Kinoite without troubling myself to overlay crucial apps that aren’t provided or don’t work fully) as Flatpak.
