Best Windows laptop out there

I'm looking for the best possible Windows laptop out there for my grandpa who is due for an upgrade to his decade old Acer. He is too stubborn to learn a different OS, hence Windows is required.

Sorting laptops by highest score on The Verge:

1) 15" MBP retina
2) 13" MBA 2011
3) 13" MBA 2012

Samsung's 9 series look great but the reviews state it's just decent. I require better than decent.

Requirements:

15" high quality screen
SSD
plenty of RAM
(most importantly) EXCELLENT build quality

The way I currently see it, my best option would be to buy a 15" MBP running Bootcamp. Which is kind of weird.
