Honestly no idea. I just found it by seeing that it was near the top of the recommended distro lists on ... some distro list website, and decided to give it a shot after reading the description.
What bought me over was that it's supposed to be just a solid distro based entirely on Debian Stable that happens to include a good few "MX Linux" tools, like the delivered nvidia driver install script, or the backup ISO creation, and whatnot.
Unless I'm misunderstanding something, it's supposed to be basically just Debian Stable with extras for convenience, and unless I'm misunderstanding/experiencing Debian, they've done a decent job. It's beating the shit out of Manjaro and Ubuntu, but those aren't exactly high bars, IMO.
