I have very mixed feelings about this.
First, I want to agree that the current state is not very fair, as “Workstation” is presented as “Fedora” and the rest is a “Spin”. I attribute 50%+ of GNOMEs marketshare on Fedora to this presentation.
I think KDE and GNOME are both awesome desktops, COSMIC will likely become one in 1 year or so. So I would agree wirth @bonsai465 to have 2 Workstation Desktops.
I also agree with @bonsai465 that KDE is a good second best experience, where things like Budgie are not as polished.
I dont agree at all with @steiner that Brodies audience, just as people actively writing here, are GNOME-haters. They are enthusiasts, just like enthusiasts would more likely use a “Spin” than “Workstation”. And I think that KDE has such a big userbase, even though often treated like “the ADHD desktop” is remarkable.
I disagree with @barracuda0207 as the stated points where GNOME is similar to MacOS are things I wouldnt even think about. There are a ton of similarities, just like KDE is in many parts a Windows clone. GNOME and KDE are not 100% innovative and that is okay.
I want to stress that the KDE Plasma Experience on Fedora is great, I highly prefer it over Ubuntu based OSes.
I agree with @farchord that KDE is just as close to the edge as Fedora, and both are a great combination.
I agree with @tqcharm that having “Workstation GNOME” and “Workstation KDE” may be too complicated for many users. I would just add short videos of the Desktops, say “both are nice, use what you want” and call it a day.
I really like this way of presenting as mentioned by @barracuda0207.
I can imagine that letting people decide “by intuition” could lead to many people using KDE, even though they might prefer GNOME. But thats just a small thought.
I really like the comment by @doomsdayrs about neurodivergent experience with GNOME and KDE and think I agree.
I would be hesitant to install something so untraditional on old peoples PCs, but thinking about it, its actually so much simpler. Pressing the home button, or the Meta key is basically the same.
