Hi,
Sorry to confuse you. The post is actually meant to be for people who come from ST and move over to Atom. There is no particular useful feature I am aware of (except maybe the git integration) that requires everyone to make the switch. I just wrote this post to show how I use Atom now and that it basically capable of everything I liked about ST. It's not really this is better than that, it's just that I have now two editors that work great for me :)
