"non-ubuntu 'store' programs"
You mean some 3rd party 'app' from the Software Centre? If so, It would have been nice if that had been 'caught' before 15.10 was released, but hardly an indicator of whether an OS is stable or not.
This might have been the responsibility of whoever submitted it, not Ubuntu/Canonicals.
Ubuntu is moving to 'Snappy' packages in a release or two, which should prevent those issues in the future.
"Luckily for me, I still have a fully functional Mint system."
Yes, lucky. You found the token problem you were looking for so you could dismiss an entire OS as 'refusing to work'. Although it doesn't sound like you even use Mint much by you choice of terminology.
With Linux, drivers mostly depend on how well (if at all) the kernel supports the hardware. If you have mainstream hardware your generally good to go, no fuss. If you have something exotic or very very new there is a chance of issues as hardware vendors rarely consider it worth the effort to provide anything at all.
