I agree with those have mentioned...
TPC Sawgrass 17
Yale 18
Engineer's "2 or 20"
And I suspect that most every solo Desmond Muirhead design has got a hole that is as controversial as health care.
I mean, in his canon, he's got a floating buoy green, island fairways, and paralleling greenside bunkers formed to mimic a shark's mouth separated from their green by 5 yards of water on each side. I've played his Stratford, CT "Oronoque" and his NJ "Stone Harbor", both of which are the craziest things going. And I know he's exceeded those. I realize he's collaborated with Nicklaus on some of the Bear's early signature designs (Muirfield) but that is damning with its own faint praise, I suppose. I can't imagine an architect more personally jealous than Muirhead probably was when Pete and Alice unveiled Sawgrass. He was devastated and he probably thought to sue them both, saying to himself "All this!? My idea!!!".
On the provincial side, any of the golfers on our board who frequent courses in Westchester and Fairfield Counties of the metro-NY region realize there's a bevy of lesser-explored quirky courses and quirky holes that could take up 18 legit positions on such a list. Of course nothing is as "controversial" as TPC 17 because of its profile, but I want to mention one of those holes.
- "Kilimanjaro" 4th hole Pequehenockonck GC North Salem NY. - this must take the cake because of all the things a controversial design can encapsulate, Kilimanjaro has a trump card...you don't even know where the hole is the first time you play it! You look at the card a second time and confirm that you are standing on the correct teeing ground and that the hole is only 130 yards long...so where the hell is it. After minutes of true indecision the group behind is starting to press on the 3rd green when they take pity and say..."the hole's up there." They point to scrubby cone like hill that looks like a rock cliff about 80 feet above you about 40 yards on the other side of the course's entry road. You cannot believe it and the elevation is so steep from the tee to the green that no flag or sense of green area is remotely possible. It's impossible to judge club, and you just sort of hit a mid-iron up there and it rarely works. That's bad because outside of the green (which actually has a large exposed rock sticking out 3 inches through the putting surface in one sextant) there is nothing but dust, shrubs and broken ground. The "rough" is just fescue allowed to gro wild since the time of Old tom Morris. It's hit the green or else and it's less fair than Sawgrass because you cannot even see it.
