I haven't tried newer versions of Windows, but the 2008 Dell workstation laptop I used for a few years was more stable under OS X than under Windows 7 or Linux. Windows 7 had an issue where the laptop's Quadro graphics card would blue screen whenever power management kicked in, that to my knowledge still isn't fixed in driver updates (the community "fix" was to keep the card running at full speed all the time). Under Linux, the graphics was an issue too — nouveau gave lackluster performance and proprietary drivers would periodically lock up. Hackintoshed OS X (10.9 Mavericks in this case) just treats the card as an 9600M GT and runs it without issue. No panics, no lockups, and no performance hit.
