This is just about my mix for Scala. I have keybindings in Intellij fairly close to what I use in Emacs, and both will update when files are edited. I drop into Emacs when I have heavy editing, need to bounce around multiple buffers, or trying things out in the REPL. I also work in a number of non-JVM languages in Emacs, and have used it for quite a long time. For JVM work, IntelliJ is, as you say, 'a little more productive'.
