It's kind of a wide disparity for something that's so locked down, though. It's not as though one person is saying they get occasional issues and the other is they often have issues... it's one person basically saying their own personal computer is nigh unusable and the other providing an example of a large number of examples of that being extremely unlikely...
It's far more likely this individual is fucking up their computer on a regular basis, or has a very high bar of usability that is broken any time there is even the slightest hiccup or inconvenience.
