Photographer Ron Donson has graciously allowed me to post images from his profiling experiment. Here they are. Decide for yourselves which sandwich you prefer. Both images are copies of the same file, one was left in AdobeRGB, the other had a profile I made for Ron assigned. Both images were then levelled out identically (by numbers) resized and converted to sRGB with relative intent, and posted.
Please copy-paste the following links for downloads. Tabs are neat for flicking back and forth between the two images.

I'll let you vote in the comments for which you prefer.

This is an interesting experiment.
I'll give you my personal opinion after a quick glance.
I like tomato A. While it is relatively pale compared to the Tomato B, I think there's more potential with Tomato A than with Tomato B.
There seems to be a bit more detail pulled out of the lower midtones and shadows.
While Tomato A seems to be a tad heavy in magenta, Tomato B seems to have a more noticeable yellowish green cast across the board. Also it seems Tomato B is a bit heavier in the shadow rendering.
I like Sandwich A best, since it looks most natural, at least on my recently calibrated laptop.
It is obvious which image has been profiled. The poorly made profile results in color shifts, color clipping, and it also has an adverse impact upon exposure. A methodical method of target preparation, exposure, and conversion has not been followed.
