Not really an answer to your question, but more a general observation 
regarding the base curves.

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".
