I have been using VS Code for a year or so and it really is worth checking it out if you do JavaScript development. It has very nice IntelliSense, out of the box linting, and the best git integration I've seen in any IDE, period.
It also is a lot faster than Atom, Atom is fairly fast in OS X, not so much in Windows. VS Code is super snappy in any OS.
I have mostly use it for Angular and Node development, a downside is that it feels very inferior to Atom and Sublime when it comes to React development. I hope React support gets improved.
