True ediff, vc-dir, and ecb are all in there. And I can only speak for my own work-flow but with each of those I needed to make modifications to have it work in a way that I liked. And ultimately never got to a place where I was totally happy (except with ediff).

I do believe that people have gotten it configured just right and that they are extremely productive with it. But for me there was just always one more thing that I needed to do from change the appearance slightly or override the annoying way that vc-dir takes over existing windows. I end up just wishing that the defaults were a little bit better.
