One thing to keep in mind: the basecurves give *one* interpretation of the raw data, not *the* interpretation. And while it provides an easy starting point, there are disadvantages: I noticed that in my case, the automatically selected curve (Sony-like) threw away about 1 stop in the highlights. And there are more basecurves that behave that way. So following the camera maker's taste has its issues...
