SilkyPix's default has blown out a number of areas on the pic. His SilkyPix custom is 5 times as bad. Even his custom RSE isn't blown out as bad as the default SilkyPix. The default RSE has very very little blown out.
I have no desire for a RAW editor to blow out my colors, thank you.
The "default" settings of a RAW editor are meaningless, IMHO. I'm glad to see that he did compare custom tries. But this is also fairly meaningless, since it would only be fair if the user is knowledgable in both, and equally knowledgable in both. Then there should be very, very little difference.
RAW editors should only be compared by the workflow - the ease and time it takes to get to the best processed file. Of course, features should also be compared - things like RSP's Vibrance and Highlight recovery, and CS2's ability to fix Chromatic Aberration. Besides specific features like those mentioned, any 2 RAW editors should be able to produce very-near-identical processed files.
