I own both, the Mac OS is without doubt the more stable platform (although it is still far from bulletproof). But Macs cost literally twice as much as an equivalent PC. And any platform is only as good as the software available, so think long and hard about what you want to run on it. If you just want it for very standard functionality (web, email, office apps), and are lucky enough not to have to worry about money, then the Mac is the way to go.
