DistroWatch published a review on MX Linux 21.

MX Linux 21

MX has its roots in users of the discontinued MEPIS Linux distro, as well as antiX, a top-notch, low-end hardware distro that is similar to Puppy Linux, but can be installed on a hard drive without making your brain hurt. The two groups found common ground and released the first MX, MX-14, in 2014. It has always been based on the Debian Stable branch and has always featured the Xfce desktop. MX-21 uses Debian Bullseye, Xfce 4.16, and the 5.10 kernel, in both 32- and 64-bit versions. There are also 32- and 64-bit Fluxbox versions (which were added for the first time for this release) as well as a 64-bit KDE version. MX-21 is supported until June 2024.

I purposely used a 7-year-old laptop - a Dell Inspiron 11 3147 with a touchscreen - to test the 64-bit Xfce desktop. That's because MX describes itself as a mid-weight operating system, so it's not as frugal as antiX but should still be able to work on less modern hardware than Ubuntu or Fedora. As such, the system specs call for at least 1GB of RAM (2GB recommended), 6GB of hard drive space (20GB recommended), and a "modern" Intel i686 or AMD processor.
