So the author mentions that the reason for picking KDE was its screen management. I feel like KDE does not get enough credit for that. I'm on a laptop. I regularly switch between two external monitors at home, various projectors, and of course using no external monitor or projector at all while traveling.
KDE remembers each individual set-up, so once I have arranged my two external monitors, I know that the next time I plug them in they will automatically be arranged the same way. Once I have set up a particular projector to be virtually above or aside from my laptop screen, it will have the same arrangement next time I plug it in. This should be the default but back when I switched to KDE a few years ago none of the other environments I tried gave me this experience (I hope it's better now). And indeed, is was the main motivation for me to give KDE Neon a try
