The KDE Plasma 5 desktop environment is a traditional, modern interface that is similar to Microsoft Windows. It’s currently the version 5 iteration of the desktop, and ships on all major Linux operating systems, as well as BSD and other Unix-based OSes.
In the Linux community, many distributions choose to ship KDE Plasma 5 as their primary desktop. That said, some do it better than others. This list shows some of the best to try out.
