Atom is so slow it's a sideshow. It also has the problem of jEdit and Komodo, not a native app so they greatly reduce battery life on laptops.
Just because Sublime's developer isn't updating it as much as he used to doesn't mean anything. What more could you want? The community hasn't stopped with plugin development which is what really counts.
This just reminds me of the consumer software mindset where a new version needs to come out every year, just for the sake of it. There's nothing wrong with using 'old' software that just works.
Then you apply an exponential curve and one day the much larger development community and Moore's Law push Atom past Sublime.

Note, I own Sublime and still use it. However, I do see great value in the Atom project. Developers shouldn't fall in love with an editor. Key bindings perhaps. The ideal editor would let me turn it into vim or Emacs, for example.

You mean like vim-mode is already existing in every editor worth to be called editor?
