I recently installed kubuntu with the latest version of KDE Plasma and was blown away. This is by far the most polished linux experience I've ever had. My girlfriend who is definitely not a linux user forced me to install it on her laptop too after seeing it.

Everything "just works", even more than macOS IMO, and you can configure everything to your hearts content. Animations are smooth, UI is very polished and consistent. Definitely recommend checking it out.
