Could you highlight some of the reasons you liked it?
* "Feels right". The ergonomics of the keyboard interaction Just Work for me.
* Excellent git integration (with plugins) which is frankly abnormal on editors that run on Windows as well as ix (or Windows at all - the git story on Windows is still pretty crappy).
Good plugin management and libraries of plugins.
Being able to style whatever you want with css is handy too, though sometimes it's tough to figure out the right css selector to use.
