I have too many. But it works well for me. I've worked on too many languages with the same editor, so I've got... Front and back-end JS tools (linting, tern autocompletion, builds); clojure with a repl and parinfer, paredit; some rust and elm plugins that can probably go since I just experimented with those mainly. Linter for terraform. I also use atom for general note taking, so I've got a couple plugins for that.
