Windows for development isn't nearly as convinent as OSX. Yes there's lots of customization you can do to make it bearable. Powershell isn't as awful as CMD, but projects aren't supporting Powershell as much as bash any time this decade AFAIK.
The Linux subsystem works, but the flow between Windows and Linux is lacking.
I tried Linux. Linux doesn't handle my mix of high DPI and normal DPI monitors (every month I'm told Wayland is going to support it "soon") so I can't use it. I know that sounds silly, but my monitors are a huge part of how I work. Not supporting my workspace is pretty much a non-starter. But to seal the deal it also crashed going to sleep a few times.
So I installed OSX... on my Zenbook. Because somehow OS X managed to handle my hardware better than Ubuntu had (bar the stock wireless card), and it was developer friendly.
I prefer brew to apt-get. Yes, apt-get is vastly more powerful, but I never had brew fail on me because a previous install had messed up.
OS X also has a lot of mindshare. Tooling tends tend to progress from Linux and OS X in ease of use before entering a gulf and reaching Windows eventually.
I got my copy of OSX legitimately, but to me it's telling I essentially had to go to "bootleg OSX" to get my hardware and software experiences in sync. OS X even supports the touchscreen as a mouse, not that I ever used the touchscreen on a laptop that only supports the laptop form factor and no others...
