Windows or Mac?

In my company we used to change PCs every 3 years or so. iMac 2006 I gave to my colleague? Runs fine. Every Mac Mini Bought even 5 years ago? Run great.
Oh and that girl who had a bug a day on PC? I never hear from her anymore.
No crashes, no restarts...
On a professional context MACS are better and cheaper in the long run. Want to game? Get a PC, they can be ridiculously powerful for cheap, but not stable.
