I’m a Linux user since 2001, I saterted with KDE 2.2 or something. I stopped using it in favor of Gnome, XFCE and recently fluxbox over the years.
A few days ago I decided to give it a try again and I have to say I’m impressed. KDE has reached a level of sophistication I had never seen before in any other Linux desktop environment. For me the experience is almost on par with macOS and slightly above windows.
