Microsft versus Apple? Help

I have an opportunity to buy either a Microsfot Surface Pro 3 or a MacBook Pro. They both an very similiar specs. I have a couple of iPad's and an iMac already as well as a couple of Windows Laptops.



The question is what would you buy? The Surface Pro 3 or the MacBook Pro?



This would be for personal use at home and the kids would not be using this one.



Thanks,
