Depends; some people look ridiculous with any sort of beard or just can't grow them, and at least 75% of guys with beards look absolutely terrible. I have a pretty short and well-maintained beard, and so far I've only come across one person that doesn't like the finished thing (although some people didn't like it while it was growing in - myself included). That's bound to happen, though; some people just don't like facial hair, no matter how well-maintained it is.
Basically, there's a difference between growing a beard and being too lazy to shave.
