You know what you're doing, which means, you'll be just fine, plus you customized your system so you're not using their stock config, anyway.
But for a newbie, who has never used Linux, coming directly from Microsoft Windows - Mint can be an absolute nightmare.
I worked in Consumer IT, and if the consumer wanted to try Linux, part of our jobs was to help them do so. We had a few distros that we would recommend, and anyone using Mint, switched back to Windows in record time.
Debian, now that they've embraced non-free (not just the separate ISO as a side-project) is certainly improving for their newbie friendliness. It is not there yet, but it would still be better for someone wanted to use Linux, and has some technical skill.
