I have been meaning to Subsystem for Linux that since they announced it, but Cmder (Conemu) has been so working well for me that I have gotten too complacent to even try it. Cmder was the one thing for me when I switched to Mac that truly made the transition painless -- I thought I would hate not having OSX Terminal. I don't do super advanced unix shell stuff, and it was just perfect.
If your needs are already being met, it's sometimes hard to make time to play with something that does the same.
It works pretty well for command-line use. If you need X at all, you're probably SOL.
I've been doing mostly C++ & Python development. I've run into a couple of issues around networking and a couple of UI issues. The UI issues have been fixed after I reported an issue on GitHub.
All in all, it's been a fairing great experience, and the developers have been very responsive to issues reported on GitHub.
I use both Linux Mint and MacOS on a daily basis and I can't say that one really is better than the other. I'm sure it would be the same with Windows if not for the fact that I need some unix-y stuff.
I do have a use case that I would really like to get on my primary laptop that neither Mac nor Linux currently offer: Detach screen and use stylus to annotate pdfs. If I was using windows on a surface this would be a major part of my workflow, and I would find it impossible to switch back. Doesn't prove that Windows is superior. (Maybe I will end up dualbooting Windows and Linux on a Surface or Yoga or some such thing eventually).
