Arch has an installer these days. It works pretty well and you can have a system up and running in about 20 minutes if you have a fast internet connection. For people that want a Windows like UI, I would probably suggest Cinnamon. It works pretty much like Windows 7/10 without all the visual nonsense that KDE typically has.
My experience is that KDE 6 has very little visual nonsense right out of the box. 4 and 5 did have a lot more, but most/all of it could be disabled. Most other Linux DEs don't really let you customize them to your own personal level of nonsense at any rate.
Stock Konsole on the left, stock Ghostty on the right. Note that both terminals have multiple tabs open. The amount of wasted space and visual noise in Konsole is baffling. Not to mention Ghostty is able to display 4 more lines of actual console output (you know, the whole point of a console).
In my experience, many KDE apps follow the same UX. Great for configuration and being able to use primarily the mouse, bad if you are more interested in a keyboard centric flow with a focus on the content.
