But for the simple case of "I need to ssh around or pull some files with curl or check something out from github or whatever and I don't have my linux box" it works great.

Cmder[0] is what I use, it supports all commands that I use on my work MacBook. If I need something Linux-specific like imagemagick, I just use WSL[1]. Some say it's slow but it runs fine. Maybe it's the fact that my PC is like 10x more powerful than my MacBook Pro because it's standard desktop computer with water cooling.
Bottom line, as someone who is using both every day - Windows is fine, it's not 2010 anymore.

If I had to use a Mac all day I would miss all of the simplicity of using Windows for things like browsing files, managing application windows, having buttons with actual labels, etc. I would miss being able to operate the entire OS with just the keyboard, which is impossible on a Mac.
