For hubby, clean shaven! His facial hair is really stiff & even just a few hours after he's shaved, it feels like he hasn't shaved in a week.
Now as far as celebs... It depends. I think Hugh Jackman is hot, especially as Van Helsing or Wolverine, both of which were scruffy roles. But Johnny Depp, I really don't like the scruffiness on him, not even as Captain Sparrow. I dunno why, I'm a bit weird I guess.
