I personally cannot think of any course mostly designed and mostly built by one person or group of people to be "great." Most "great"courses are mongrels. Even the best of the most recently built exceptional courses (e.g. Pacific Dunes, Friars Head, Castle Stuart, Trump International, Sand Hills, etc.) have their imperfect idiosyncracies, as do the oldies but goodies (Pebble, Augusta, NGLA, TOC, Dornoch, and possibly even Pine Valley (which I have never seen)).
To me, one of the beauties of golf is it's imperfections.
