It depends on the guy, actually. Some guys have wiry, painful facial hair, some (like me) have soft, fine hair. Unfortunately, the painful hair is usually the one that looks better, my "soft fine" hair looks like pubic hair.
Plus, I have this weird tri-color thing going on -- blond moustache, turning gray under the chin, dark brown pretty much every where else.
Even after all of that, it still looks better than clean-shaven.
