Sublime is a great editor. I purchased Sublime many years ago and improved my ability to work. Now I'm using Atom because I like the way it looks, it does everything I need it to do, and while it may be slow to open, I leave it open anyway so it's not really an issue for me (note: Of course I want everything to be as fast as possible).

That said, I still support Sublime and would still even buy the upgrade to the new version if it ever comes out.
