Microsoft or Apple Macintosh?

Seriously!! I want an answer: which one crashes less and is more performant? mac or pc? because I currently have a vista and it's the worse computer I've ever owned, it crashes every third day because of "software updates" and freezes whenever it wants. So now I'm thinking of making the switch to mac hoping I won't have these petty problems and crashes. So tell me, is this a good idea? is mac truly better than pc or vice versa?
