Windows has plenty of warts that I doubt WSL will resolve (can't delete open files, spectacular suicide if you use symlinks or junctions on system resources, different administrative abstractions and CLI tools, that sort of thing) but I might be willing to give it a spin if someone other than microsoft says nice things about it.
I don't buy the "I've used OSX for so long I can't possibly adapt my workflow to Windows" argument. It took me a few days to get used to the new idioms, but it wasn't that bad. Then again, I've been pretty OS agnostic for my career - Irix, SunOS/Solaris, Linux, OSX, and now Windows+WSL. Other than the part of my career when I was doing systems research and had to care about OS-specific details (e.g., writing Linux kernel modules), I haven't really found it hard to adapt to new environments and be happily productive.
It isn’t perfect, but it’s good enough that I don’t notice the warts too frequently. I’m not very fickle though: at this point in my career, I’ve come to the conclusion that all systems suck in their own special ways.
