I switched from Emacs to both LightTable and Atom full-time. While I'm much more efficient in Emacs, integration are the killer features in the other two, in a way that I didn't have my .emacs setup.

With LightTable, I do mostly WebGL and I often have a browser tab up with my live WebGL stuff all the time. This is super efficient and extremely nice.

With Atom, I do mostly web development. Quickly jumping between files (faster than I did in Emacs) and knowing which files have been changed (they're highlighted in the tree-view) is very helpful for all work-related things.

How is it faster than Projectile? Demos in here: http://tuhdo.github.io/helm-projectile.html. With Projectile, I can jump to any file quickly, even with source tree as large as Linux kernel with more than 36k files. If a file is in a project, regardless of where I see it, even in a plain .txt file, I can jump to it: http://tuhdo.github.io/static/helm-projectile/helm-projectil...

If you want that live web stuff, you can try skewer-mode: https://github.com/skeeto/skewer-mode
