I used Sublime for a while, then switched to Emacs for a while. I ended up switching back because, while I really liked Emacs, I didn't like being stuck in a terminal and I couldn't do effective pair programming.

The best bit about Emacs is the configuration, and I could give or take the awkward keybindings. Maybe if LightTable supported configuration with ClojureScript and offered a comprehensive API for it there'd be a more modern equivalent.
