I feel comfortable with all the UIs, but essentially I want to be as close to my application's production environment as possible, while still being productive. I've never worked on a team where that environment was windows, and setting up node/ruby/docker/vim/bash/nginx in a windows environment has always been a total pain compared to either linux or OS X (still kind of a pain for docker, but slightly less so).

For some of these core tools, authors explicitly state that windows is a second class citizen. It's just not worth the expense to support something that has so few comparative users, in some cases (ruby). It's a lot of work for something that will never feel "native".
