MX Linux MX-21.3 Wildflower - Thorny elegance
I chose to start with the Xfce version. After all, MX Linux is all about being frugal and light. Now, now, now, this used to be an important distinction re: desktop environment a few years ago, but it isn't anymore. Back in the day, the so-called "heavy" desktops would indeed be heavy, memory usage and performance wise. Nowadays, the underlying distro choice is probably more important when it comes to system toll, i.e., Xfce alone won't do miracles. The gap to some of the heavy desktops has also narrowed a great deal. You want speed and all of the modern conveniences? Plasma. When it comes to lightweight, both Xfce and Plasma will deliver.
