It's also the easiest to extend, modify, and generally make into the perfect(if slow) editor.
Also, it has the prettiest themes. But I'd be fooling myself if I didn't say I'm keeping a serious eye on NeoVIM to possibly alleviate me.
Did I have to adjust my workflow a bit for it? Sure. But honestly, the dividends its paid in terms of making it easy to create snippets, easy to fork and extend addons, and in just making me smile through dumb pretty UI things is totally enough. And the vim folks that use it and keep pushing it further and further are having a good time, 'cause aside from a few buggy commands it's a joy to vi around Atom.
Like I said in my original post- it's slow, but you can make it the perfect(if slow) editor if you want to, and that's pretty well.
I really enjoyed using light table for a few years but not working in clojure, the integrations were never really something i explored to make the weight worth it, and it often had issues with freezing for fairly simple operations.
