I split the difference. I use Vim if I'm in a server somewhere or if I'm already looking at the command line for git or ag or something. I usually use Sublime when working on a whole project at once.
I certainly don't begrudge you your workflow, it just doesn't match mine. I manage my entire project from a combination of vim and shell, to the point of running my tests from my makefile and making sure error messages have meaningful (in so far as is possible) file:line: info in a format vim will understand so I can easily jump to meaningful pieces.
