It really depends on the guy. Some men look 10000000x sexier with facial hair than clean shaven. Others can't wear a beard for the life of them. The guys who grow it out, and there's not much there to grow, for example. If you can count how many individual hairs are on his face, the beard failed.
Not gunna lie, I quite like a bit of a beard. Not long enough to brush or plait, but long enough to thoughtfully rub when you're deep in thought. On guys, I mean, obviously I unfortunately do not have a beard that I can thoughtfully rub or indeed comb and plait.
