Sublime 2 is bulky, slow, and not very feature-rich. If you're going to use Sublime, use 3 for the extra speed and space increase. Also the API for 3 doesn't suck.

Though if you're going to use anything GUI-based it should be Atom. It's not super memory-efficient because it uses Electron, but it's super customizable right out of the box; has a great, rich, easy-to-use, and well-documented API; and has direct integration with NPM and Git.

agreed. Why did people stop using Vi? It's incredibly lightweight, designed for writing code, very powerful, and easy to use (when compared to its competitor editors)...
