This is the one app I use every day. I practically live in it. Most editors are slower and more visually cluttered, or pack so much functionality that I often get lost. Sublime strikes the perfect balance between simplicity and functionality. Probably Emacs or Vim are even more expressive, but I've never bothered to learn those, Sublime just packs enough power for me. The LSP plugins are a good addition to give Sublime the same code completion / AI functionality of other editors.
