Dell XPS 13 vs Lenovo Yoga 720 13

So I'd been fairly set on buying a XPS 13, but I recently stumbled upon the Yoga 720 13 inch, which seems to offer a fairly bigger bang for my buck.

I'm looking mostly for a portable, well-built laptop with a well-callibrated screen and a long baterry life around USD 1300. Which one of these do you think would be a better choice?
