I don't see how you can make a categorical statement declaring that as long as drivers are written for OS X, OS X is more reliable than Linux.
Hackintosh != most people's experience of OS X.
Your experience will be particular to the hardware you chose, and the implementations you chose to follow.
In the same sense, I wouldn't declare that Linux is more reliable than 'X' because again, there are far too may variables involved to make a fair comparison.
I think a far more pragmatic approach is to accept that Linux can provide a very robust desktop solution - if the necessary investment in time and research is carried out. Largely, imo OS X is successful because this research has already been carried out on the users' behalf.
