I use Arch with KDE Plasma and it looks like a clean version of the traditional desktop you’d expect on Windows, with a bottom taskbar, start menu, etc. But with a really clean theme and tailored to my needs.

My wife is also using Arch with the exact same KDE Plasma version… But hers looks exactly like a Mac, with a rounded translucent dock, a menu bar at the top, widgets, animated wallpapers and so on.

So yeah KDE Plasma is amazing, it will adapt to your exact preferences and not get in the way.
