Windows has always done what I need it to do and without issues for me.

The same with my Macs.

Both run some software that the other can't run, and both do some things better than the other. So I'll continue to use both because neither is honestly better than the other.

The difference being that my Windows machines are less money vs. the performance and don't look as good, and my Macs are the inverse of that.
 
Gaming. If Steam were ported to OSX I'd have no reason for custom built rigs any longer. *sigh*
