I’ve used both, and prefer the Surface Laptop to the X1 because the X1 screen and keyboard were garbage (blurry pixels and squishy keys).
I work at Microsoft and was issued a Lenovo, then got a Surface Pro 4 and finally a Laptop. Everyone in my team who got the Book instead is a little sad because it’s a huge lumbering beast compared to the Laptop and tends to be top-heavy compared to the X1s and Yogas we had. Those of us with Pros (tablets) and Laptops love the portability, even if you only get one USB port.
Also, all the Surface trackpads are MacBook-grade (although the software handling might need some tweaking for you to get exactly the same feeling - but I’m happy with mine now).
