It was certainly an interesting exercise and at the end I concluded that the programmed auto settings are extremely realiable and it's probably more important to have the correct lens, flash, & lighting. If you're after a particular look or effect then the manual settings can deliver, but if you're looking to take a solid photo with a minimum of fuss then be prepared to trust the auto program settings. Just make sure you select the correct option, have good light, and let the camera do the rest.
This photo was taken using a Canon EOS600D on a tripod, with a 50mm lens (macro) and external flash. The camera was set to "P" for Portrait.... and yes, there was some touching up done in Photoshop ;-)
