I know for myself, and many others at the companies I have worked for -- THere are a signifcant number of people who use Macbooks, but run Windows on them. As I type here, It's a macbook Pro Running Windows 10.
The hardware runs Windows significantly better than any natively developed Windows notebook. Probably becasue drivers can be written to only a single known configuration and that can be optimized.
WHen running multiple VMs, and IDEs on Windows on Macbook Pro hardware -- it simply outclasses the same setup on alternatives.
But either way, at our office, more than half (500+ users) all run Windows as their primary OS on the Macbooks. Most workers don't know that they can even boot into Mac OSX (minimally sized partition, as even the Engineers don't even boot into OSX)
Once I installed Windows 7 on a Macbook Pro -- I never went back to Windows-first hardware.
1. Buy MacBook
2. Install Windows.
3. Have a kick ass windows box for development and gaming.-
