I never recommend Mint! It’s like it became this de facto distro to steer newbies toward just because it sort of kind of looks like Windows? Elementary OS is simple, polished, elegant and in a good way less customizable so the user can just get to work.
Alternatively if they want something more familiar like the start menu there’s KDE on Ubuntu or OpenSUSE, among others.
Mint was impressive like fifteen years ago; it’s still fine, but nothing in particular makes it more appealing than some of the ones I mentioned which have significant advantages.
