Are they improving the performance issues? I love Atom but I've had to switch to Sublime 3 because I can't handle waiting a couple of seconds every time I switch between files (or the several second start up time). It's small but it completely kills my workflow. I spent the whole weekend setting it up to look similar to my Atom setup, including implementing the same syntax highlighting. It's not perfect[1] and feels like it could fall apart at any moment (eg I had to do an awkward hack to center text in tabs), but it's worth it for lightning-fast switching between files.
