D700 ISO 6400 with three different RAW processors

I took a single ISO 6400 D700 NEF and converted it using three different popular RAW processors. As a hint, I'll reveal that all three are available for both Windows and Mac.

In each processor, I set both sharpening and noise reduction to "0", "Disable", or whatever the minimum amount was. Otherwise, settings were left at the program defaults.

Poll: Which do you think is providing the best "starting material" for processing this image? Ie, which one do you like the best: top, middle, or bottom?

Here is the center crop from each:

Bonus points to anyone who guesses the app used for any/all of the crops without cheating. Those of you who know the answer from another forum, please don't give it away yet...
