Smell/looks:
1. ksufans. By far. Young, virile, fresh scent of posters. I've met about 25 posters from this site and have never been disappointed with the eye candy. Sexiness abounds.
2. tie. Both have old'mannish BO stank. Disgusting looking and cranky for the most part.
Luckily, for steve dave, we've never met. Unfortunately, I
am an old man (

), but I try to make sure the old-mannish BO stank is not present. Probably don't fit into SD's eye candy clique, either.
However, I make up for all of these shortcomings by being the resident classless admin and resident cycling expert. Of course, KSUFans has superior Tour de France coverage and commentary*. And the other two sites are just too 'classy'.
And on a more serious note, Terry Pierce, of DoD fame, is owner of these boards. The other two sites cannot match that.
*of course, since the other two sites don't have cycling at all...
