Alright, I wade in with my nominations for each...
Looks bad, plays great---this is a tough one, because the "look" is clearly objective, so I might re-phrase it as "appears uninspiring", plays great, OK?
then I would nominate Holston Hills.
the overall appearance when I was there would not immediately jump out and grab someone, and might be considered on the humble side, but after finishing there was definitely a strong desire to head right back out to the 1st tee, and the course played great!
Looks great, plays bad--Sahalee in any combination is a poster-child for this one. It has a visual look that is breath-taking and arresting, yet I have found any combination of the 3 nines indistinct and unmemorable, and the course is situated in an architecturally unremarkable housing development as well...
