I always prefer facial hair. 999 out of 1000 men look better with SOME kind of facial hair, in my opinion. But it's just like styling hair on the head; some styles work for you and some don't... so just find the style that suits you and you're golden.
I love every style from barely unshaven to full beards... EXCEPT I don't like mustaches or soul patches, haha!
I don't really like it much, but some guys actually look better with it. I usually don't like it because I'm new attracted to pretty boys. Don't get me wrong I love manly men. But the pretty boy, baby faced look.
