I agree with Lian Pretorius about the Sales wow factor. I built 2 public facing sites on it and hated it for a long time, but after about a year it seemed to look after itself. Workflow is nice and the fact that the built in search will index word documents. Though the effort in bending it to do what you want rather than what comes out of the box makes you think (regularly) - if it doesn't do what you want, haven't you bought the wrong thing in the first place?
