As you know, the basecurves are supposed to imitate the processing of specific camera's (or brands). Or, applying the basecurve for your camera (brand) should give the same result as you would have gotten by setting the camera to produce a jpeg. As far as I know that is exactly how the basecurves are created: take a raw and an in-camera jpeg, and tweak the curve until the processed raw looks the same as the in-camera jpeg. If that's what you want, that's ideal. But that processing isn't necessarily the best for every image. Personally, I use a Sony A58, but I rarely use the Sony basecurve, as I feel that it compressed the highlights too much. Instead I pick one that suits the image (to *my* taste). The DT manual actually suggests to /disable/ the basecurve module for certain cases, so it's not a necessary part of the workflow (unlike e.g. demosaicing). So the whole notion of a "better curve" is a bit meaningless to me, unless you can specify what you mean by "better".
