I can also vouch for Plasma. Today I checked the uptime of my computer, and it is doing 16 days running Kubuntu with no issues, and it could be months if I was not rebooting to get system updates. From my personal usage perspective the stability is somehow like this: ios > Gnome > Plasma > Windows = Android Considering that both Google and Microsoft platforms are giving me more issues, I would say that Plasma (and Gnome) are doing quite well. And not to speak of the actual usability, for desktop I'm yet to find something better than Plasma (I don't use macOS nowadays, but I had a great time back when I used Tiger and Leopard).
