I'm using Ubuntu with KDE Plasma. A while ago, Windows reset a lot of my system (thank the powers that be that my files stayed intact), and I decided that I was fed up with Windows and that I'd find a way to continue everything I was doing on Linux. At this point, I'm roughly 95% of the way there as I do own an Oculus Rift which only supports Windows (unless someone can point me to an article or forum post that says otherwise); I'd like to either get a Valve Index or a Quest, but I don't currently have the money.
In any case, a friend of mine recommended a flavor of Arch that included KDE Plasma (I forget the name, might be Endeavour) but I was coming up with issues that a lot of programs I had wanted to use were only built for Debian/Ubuntu so I switched again. Lovely how with Linux you can switch distros so easily. So I flashed my computer with Kubuntu and I haven't looked back since.
