I fully agree with you. I have converted a few “regular user” Windows desktops to LMDE in recent months. They are all quite happy and the “tech support” required has been almost zero.
The OP made “Wayland first” a criteria which disqualifies LMDE as it will default to X11 for perhaps another year.
While I agree with their Wayland comments, I think LMDE (and Mint in general) are great new user distros. Both offer “comfortable” UX for Windows users. A new user probably does not care about Wayland vs X11. Mint has made it clear that the future is Wayland and may even go Wayland by default in 2026 and they will auto migrate users when they do. They are just being conservative in terms of declaring it ready. Is that a bad thing?
There is this really strange perception amongst Wayland critics that it had low market share and nobody was using it.
The majority of Linux desktop users are on Wayland and we still have people posting that nobody is using it or even that it “doesn’t work”.
Wayland switched to the default in places where it was already popular and is becoming required in places where few are switching away from the default.
