Every version of Windows is better than running an OS that locks you into one brand of crappy, featureless overpriced hardware. Speaking on the software itself though, Windows certainly has got better, more logical window management and better tools built in for multi-display. Windows also has a logical and consistent keyboard acceleration system compared to the ridiculous hidden functionality that plagues OS X. Pretty much the only good thing about OS X is that it's Unix. Otherwise nobody around here would be using it.
