Gizmo that is not true - Yes it was very problematic years ago, but now days it is pretty rock solid (imho) Yes on occasion there are issues but often only due to some specific setting or other software you have installed. I've managed very large sites and smaller sites as well and all of them work fine with Microsoft critical updates. Microsoft is also available for free to repair your issue if the critical update did break it.
Granted many of the updates are not quite as "critical" as some would want to believe but still 99% of the time you will not have an issue with an update (imho). Which is still better than most companies out there that provide updates.
