Is it all about getting a "better" starting point for additional edits? Or is the final edit truly better with Adaptive Color (or Adaptive B&W)?
You are getting into very subjective territory, which is not worth arguing.
I assume you have read the Adobe blog article:
The Adaptive Profile
based on that, the Adaptive Profiles have
the potential to provide a truly better end result, but again, that will be in the eye of the individual view and their preconceived/trained expectations or desires.
however, I say that, still based on getting to an end result
quicker. One could still do similar adjustments to sky, background, subject, as the AI Adaptive profiles try to do, and get similar or same…or better for you…results. In the end, some one will always be able to say….well, I could have done that…as in “I know where the brightness slider is”.
