I still use Atom and it works great for me. Just because someone isn't blasting code in it constantly doesn't mean it's dead (infact I usually prefer it to constant, chaotically high levels of change). How often does rsync change and does that prevent anyone from using it?

That said if I was going to switch to something I would probably go back to sublime (which I have a license for). Microsoft is dumping a lot of money on the coding space right now and I'm really not interested in finding out why the hard way.
