Working on post processing, which one?

Hi all,
I would like a little input on the following two versions of the Running Man. I am trying to see what processes give the most realistic image.
This one I did in my normal way that I would do most images.

Then this one I did a bit different, using more curves and stretch as well as combining all colors and Luminance for the Luminance sub.
Which do you think is more realistic in presentation and why, if you would be so kind?

Even though the second shot shows more, the first one looks more "natural"... IMHO. Both are nice, but I pick the first one. 8)
