I wouldn't claim one is inherently better than the other, but I've been a Windows user (and that includes professionally, as in running servers etc) for over 20 years now, and I've never been able to really get into OSX (and I'm the appointed Apple specialist at my school, after being sent on a 4 day 'how to use OSX' course). I don't have any other Apple devices, I don't have an iTunes account, I'm just not invested in any of it.
I will accept that the hardware is pretty nice and well made though, I doubt I could have picked up an 11 year old Windows laptop (that has at one time in its life served in a classroom environment) and got it working and feeling quite so nippy (I have put an SSD in which helps). I guess a lot of that is why you pay 3-4 times the prices in the first place.
Truthfully I was just testing out the process as we're going to be decommissioning some more Apple stuff soon and there's a chance of getting a 2012 iMac, which would be so much more useful to me with an OS I know how to use on it.
