I didn't like Atom because of speed and GUI settings (got used to text settings after sublime or vim). And there are migration issues - I have a lot of plugins, settings, project files and knowledge so migration process will take too much effort.
Also, I don't think that it is a good idea to implement CPU intensive real-time applications in javascript (e.g. code parsing or syntax highlighting). There are plenty of languages/tools that suit well for it, there was no reason to pick a javascript as the primary language for a editor.
