“It works perfectly fine”
Your software packages are old (on top of being how far behind Linux in general runs behind proprietary to begin with). -This means they have less features and more vulnerabilities. Hardware compatibility sucks because of ‘old kernel’. Software support is lacking and sometimes needs PPAs or ‘personal package archives’.
Anyone with common sense can see you’re recommending a distro based on a server distro that’s based on a server distro (and surmise there’d be problems with that). Mint can’t even focus on one distro but wastes resources on a Debian version (server distro), and a desktop environment (the only one I tried and rage quit after a half hour because of the convoluted way of using their GUI). So Mint adds to the problem of GNU/Linux and the choices with not only 2 redundant versions of itself, but a DE no one needed or asked for.
Some not so bright Linux youtuber told his followers that they need to stop confusing noobs with many different distros. He suggested to pick one and go with that. -He picked Mint and not for any particular reason. -This youtuber also told us that ‘Linux is Linux’ and distro didn’t matter.
