I've never had any of my Linux boxes crash on me in the 15 or so years I've been running it. That's everything from Raspberry Pis, to desktops, to virtual machine hosts. My NAS has been running the same rolling release of Debian for the last 9 years without issue. It has been powered on 24/7 365 that entire time, the only times it was powered down were during power outages or hardware upgrades. I've since migrated my brother and my girlfriend over to Linux, neither of them are having issues. My girlfriend has been running Debian for 6 years now, I haven't had to touch her computer aside from replacing the power supply recently. I've had Windows crash more times than I can count during that period, which includes 98, 2000, XP, Vista, 7, and 8.1.
As for Mac OS, I went and installed a new router at my friend's the other day, kept the same credentials as the old one. I go to reconnect his Mac Mini and got a kernel panic when connecting to the new access point. I check the logs and didn't see anything out of the ordinary, and according to Apple, the solution was to reinstall the OS or restore from a backup. Luckily he had a Time Machine backup and was able to restore, but that shouldn't happen for something as trivial as connecting to a new access point.
