I echo some other comments... I think perhaps 10-12 years ago, I would strongly recommend Ubuntu to new users. I find now I actively try to get people to stop using it. Here at the uni professors blindly ask for it since it is so popular, but it causes more trouble than it is worth. I used to be a very large Mint proponent, but even now I find it harder to recommend that distro.
In an odd twist, my most stable builds are gentoo boxes, which are by no means built for any kind of novice, or heck, even some real linux users have issues with it. I installed and used MX a few times, and perhaps will migrate most to that distro.
Other than moving to Debian, I wonder what is a truly stable desktop distro these days, which someone could recommend for a new user? Might have to break down and start trying some cherry picked ones from the distrowatch list again...
