I think ST3 really missed the boat. I used to love using Sublime Text 2 (occasionally I still do because it is fast), but I moved on when development stagnated and Jon seemingly disappeared off of the face of the planet, stopped responding to support requests and the like. There is no disputing ST is a great editor, but it has fallen behind in the face of Atom, Webstorm and Visual Studio Code (two of which are free).

Genuine question:

What do Atom and Visual Studio Code offer that Sublime Text doesn't?

I have tried both within the last year and wasn't able to find any significant advantages (except for VS Code's excellent TypeScript experience), but they both ran slower and used more memory. Perhaps I should have used Nuclide?

(Not asking about Webstorm because I've used the IntelliJ family of IDEs and understand their advantages)

I use Atom over Sublime Text solely for the Hydrogen plugin (https://github.com/nteract/hydrogen).

That plugins are written in javascript (larger developer base) and allows more customization of Atom (more open plugin api) also yields more niche plugins.
