Facial hair, all the way--though some guys have weak facial hair, and then it looks terrible. I prefer a good, full beard or a nice goatee. And of course Tom Selleck's mustache.
My SO has a very nice beard. I'm a big fan of his beard. He shaved it off last spring but we both decided he needed to grow it back ASAP.
There is a lot of fun to be had with facial hair, after all.
