I've tried to run KDE Plasma for years, but it's just so unstable and buggy (I also think it looks bad, but that doesn't really matter). I recently had a friend that said "KDE Plasma is great now, give it a go!" so I did, and instantly broke it by installing a theme via the official themes manager, and I had lots of smaller issues, like the Steam notifications appear above the taskbar and the Steam Friends List being slow to open. I told my friend and he said "Oh, that's KDE Plasma and not just Linux being weird?" and he ended up switching desktop, realizing so many minor issues was due to KDE Plasma.

It's super responsive with keybindings and all convenience features I can hardly be bothered by these aesthetic issues like some icons appearing 69 picometers too left OR looking ugly.
