That is not a very good argument against what sneaker said.

How do you know both mixes are based on the same mastering?
How do you know the DD-mix is not willingly different/worse than the HD mix?
Are you comparing identical speaker layouts (both just 5.1)?
Are you sure there is no dynamic compression in the DD-mix?
Are the volume levels identical?
Is the DD-mix limited in bitrate (384/448) or does it use the full 640kbit/s potential?

If you want a comparison of codec audio quality only, try encoding your own DD-mix from the HD-audio stream, considering all the factors above.
Even then, you cannot be sure in case of AC-3, because people claim that the original, commercial encoder is superior to those available freely...
