When I started using TypeScript a couple weeks ago I briefly tried out VS Code, but the VIM plugin was really, really bad (worse than Sublime's was when I used it a few years ago).

Now I'm on Atom, which has the best VIM support I've ever seen (haven't tried evil-mode, though) and seems to support a similar feature set. They felt about the same speed, too, on this 2013 Macbook Air.

Regardless, other than that quirk, I did really like VS Code, and I'm glad there's more competition in the free editor space :)
