I suspect that many millions of Mint users worldwide would disagree with you, but if your bad experience so far is legitimate and not just a trolling exercise, then a re-installation attempt by you might help you make a better judgement for or against.
Millions? Who are they? I have never seen nor heard of anyone using Mint other than those on this forum. Never seen or heard of anybody depend in whole or in part any other kind of Linux either, certainly not in a business environment of any type. One exception: Dad, who was 80 at the time. The explanation of his exception demonstrates the reason.
His HD crapped out along with his Windows on his old tower, and I had just enough familiarity with Ubuntu to install it and get it going enough to recover his data. Since he had pretty low demands for a computer -- check email, on line banking, a few snail mail letters, like that -- it turned out he could use it instead of Windows just fine even though he had only enough computer sophistication to do those few things, and only because I figured out how to put icons on his desktop that took him to the very, very small number of Internet places he needed to go. He wasn't going to do games or do his taxes or edit videos or use imaging apps or even order on line. I don't think he ever used the Start button in Windows and surely he did not use what amounts to start in Ubuntu. I rendered it unnecessary.
Not too much later, he joined a computing class in his 55+ community. The instructor owned a local computer repair store and was trying to drum up some business among non-sophisticates who were likely to do some damage by dropping their laptops, failing to shutdown correctly, like that, maybe wanted to use Word or Youtube.
Needless to say the instructor was dazzled when my father asked about Ubuntu because the instructor had never heard of anyone using it. He also had no idea what it did or how to get it going, and so he started peppering Dad with questions Dad could not begin to answer.
And therein lies the problem. It is very unwise to try to use any Linux distro largely built in some high-schooler's bedroom in some non-computing business, including the most popular types, because weird and horrible and possibly irreparable things tend to happen* in the wild as they did to me. No Grub, no wifi, all day babysitting upgrades that would not take, and so on, and randomly timed Community Responses by persons with unknown skillsets to even desperate queries are just as likely to be guesses, surmise, or just wrong as they are to be helpful. Professional repairmen apparently don't have much grasp of it because there are so few calls for it, ie, a vicious cycle of no one uses it so no one can fix it so no one feels safe using it.
You are not risking your business coming to a halt on a computer crap out that cannot necessarily be fixed in a minute, day or ever, as happened to me, just to save a few bucks by avoiding/protesting Windows or Apple when buying a computer.
For a doctor or lawyer or anyone else under severe time pressure, a case could be made that it is malpractice to allow his/her business to essentially shut down for an indeterminate time by using unknown-to-the-general-public software that may or may not be fixable at all or under any kind of reliable timetable when the client's life and/or property is at stake. Anyone can have computer problems; not everyone can invite them by using unknown services with tendencies of unreliability. You certainly don't see airlines buying planes from companies few have ever heard of. I'm pretty confident you didn't buy a car from some kid working out of his mother's garage. You probably bought something that is known, well reviewed, and has a series of dealerships that can do repairs on a schedule using sensors that tell mechanics what is wrong, rather than forcing them to guess or rely on the Community to assess the problem.
And you are definitely not spending lots of time and money retraining your staff to use "it's not Windows" after someone else has paid to have them learn Windows, as most people have done since kindergarten.
*Here's what happened today. I previously mentioned that in the past couple of days, I did as suggested, ie install a different distro. Manjaro, which had no problem creating a Grub allowing dual booting but also did not recognize my wifi dongle and did not appear to any software to all the use of wifi. So I found a workaround, a relay that receives by wifi but delivers to computers by ethernet, which Manjaro did recognize.
Well today was the day to upgrade the distro with the latest patches and it did not go smoothly. The download crapped out repeatedly, though it would resume if I started the upgrade process from scratch, and I did it several times after an equal number of crapouts. Eventually it completed the download, completed the install, and demanded a reboot.
Which resulted in Manjaro equivalent of a BSOD each of the 4 or so times I tried it. I had to reinstall from scratch, and then I did the upgrade. Total time: about 3.5 hours.
Imagine if I had to effectively close my business over a routine upgrade that has to be babysat and might not work. Not really prudent.
I also still don't know if I have wifi.
Millions? I'm seriously skeptical.
