To cut to the chase:

"Attractiveness ratings were highest for bearded faces with smaller jaws followed by bearded and clean-shaven faces with larger jaws and lowest for clean-shaven faces with small jaws. "

Basically proving the theory that the people who benefit most from stubble/short beard are those with a small jaw and or recessed chin.

if your jaw is narrow, grow a beard. if u have a wide enough jaw just get a medium lenght beard to make it seem more angular, if u have a top tier jaw, just stay clean shaven or get your beard down to 2mm or even lower. thats pretty simple i guess
