KDE is the way! I’ve heard KDE called the swiss army knife of DE’s, and I couldn’t agree more! I’d be curious to see a comparison of Gnome and KDE users previous OS. I’d bet KDE has more windows converts and gnome favors mac, but I really don’t hear about many mac folks switching to linux.
Be sure to include Nobara and Bazzite, both of which are gaming focused distros. Both are Fedora based, but Bazzite is known more as a SteamOS 3 clone. There’s also another gaming focused distro, it just escapes my mind. But I love Fedora KDE as is and then just installing the required software. So I’d say add Fedora, Nobara, and Bazzite for sure!
