Longtime Mint stickler here, never developed a taste for any other distro schools (Arch, Fedora, other *buntus and Debians). But tried out MX after a long period of deferring and I am genuinely blown away. This distro has everything I could have ever ask for - Debian stability coupled with advanced hardware support (with more recent zen kernels and drivers), a solid opinionated Plasma DE setup that is both minimalist and all-encompassing at the same time, and a full stock of sensible and pragmatic utilities to cover the boring stuff.
Mint’s relative lethargy at migrating to wayland has been increasingly becoming a sore point due to the sheer practical difference it makes (especially in terms of multi-monitor HiDPI and fractional scaling, in addition to security and performance). MX KDE has all that covered and then some. It’s the first time I had to genuinely stretch to find any fault. The only complaint I have is that they aren’t letting me post this testimonial in the MX forum because it doesn’t accept anon-aliased emails for logins.
To be fair, migrating a desktop environment from X11 to Wayland is a lot of work, Wayland still hasn’t reached feature parity, and most desktop environments are maintained by very few people with scant resources. It’s no surprise that the big ones are ahead of the others.
