I'm not sure I'm much of a fan "skin shader comparison's" that include my shader, since I've got no control over whether the user is using my skin shader correctly.  Also, you comparison image is way too small to compare anything!  I doubt anyone in this forum is doing realism renders features James that small.  Give me a 600x600 render of James, and I can make a good guess if it is using my skin shader, but not on images these small.

Also, you are comparing your setup with Stahlberg's (which must be at least 3-4 years old now - and he no longer uses that technqiue!), and my original technique, which is nearly 2 years old, and doesn't represent the techniques used in the more recent Skin Realism Kits (which have significant improvements). 

My current skin shader produces results like that attached.  To me that looks realistic.  It was done with 1 spot light, and 1 IBL fill light.  I'd be happy to render that scene with your node setup to give a better comparison between the shaders.
