Consider the effects of natural airflow - required to remove heat - on each of the photographed items.
Clearly, the larger bulk & surface area of the finned item is the most efficient at removing heat.
Then consider directional, forced airflow AKA \"a fan\".
The larger surface area will win every time ( with respect to ambient temperature of course).
Soon I hope to build a reliable heat source to provide actual performance data.
I\'ve read http://www.heatsink-guide.com/heatsinkinfo.shtml (more than once). Very good.
To illustrate the points made about materials\' fundamental thermal & mechanical properties I\'ve added a pic here:- http://i65.photobucket.com/albums/h216/Ray_GTI-R/PC/Dscn3753a.jpg
Please feel free to use it and any other data included, to illustrate the points made.
