Earlier quoted context omitted.
But the perception that "shit happens way more on Arch or Gentoo" is your subjective opinion, because that's how it happened to you, others see it differently, I still remember the very first Ubuntu I've tried (6.10) being garbage on my hw compared to Mandrake, but that didn't seem to be the case for a lot of people evidently since it became so popular.
There are a lot more updates on Arch that require manual actions to be taken in order to work correctly, when compared to Mint or Ubuntu. Similarly, the config file merging process on Arch is basically 100% manual (I know pacdiff makes it a little easier, but still).
There's more, but I don't think a lot more. Also, if the automatic config in Ubuntu fails you, it's a lot harder to get in and manually override their settings.
