Sublime, people still use that over Atom? Do you see more people using VSCode than Atom, or Emacs? What about TextMate 2, no one? Which language do your backend guys use VSCode for?

2 - Atom is slower, you may think a fraction of a second when opening a file or doing a search should not make much of a difference but, when you are using an editor every day for many hours, it ends up affecting your productivity.
PS I liked VS Code but it's different enough from the other 2 editors that it would take time for me to become proficient with it. I especially liked VS Code's debugging features.
