Tom,
I can preface this by saying that I did like all the courses, none of them were a bad course, a few overhyped but all of them were good courses. It's like asking you to pick your favorite type of food when you are having lobster, prime rib, etc. for 16 straight days?
I'm not big on the "wow" factor so if a course is in the middle of Kansas or over the pacific ocean it doesn't matter to me as long as it provides different shot values, provides me with the ability to have to make shot decisions, and the routing has to be good. Subtle things like I prefer walking courses and also prefer harder courses..just personnal preferences. It's difficult to describe why you like something. Why do people like chocolate, because it's good...some better than others.
My favorites were Bandon Dunes and Prairie Dunes....mostly because both had more interesting holes that required almost every club in my bag. I don't see how a course in any location could be presented better that Prairie Dunes. Holes with the wind, against, short par 4's with multiple options (#3, #6, #12, #14 and #18), great long par 4's. A great par 3 in #2 with a demanding green. Just a perfect golf course.
Very close behind were Pacific Dunes and Bandon Trails. I really debated with my playing partner about the 3 Bandon courses and determined that they were probably all equal, there were just subtle things about all of them that you would like more. I really liked how both Pacific and Bandon Trails (more than Bandon Dunes) provided that "open feeling" in the fairways but really weren't because the bunkers were placed to just suck balls into them. So, it really required playing a few times to even realize that the center of the fairway wasn't always the best spot. Favorite hole of all 3 courses is probably #3 at Trails. I really liked how when I got to the green I didn't see a single bunker looking back at the fairway but on the tee on that hole it is littered with bunkers. #4 at Bandon Dunes was my favorite there and #11 at Pacific Dunes was my favorite (trying to hold a ball on that green with that wind was tough) and I really liked playing #17. In the wind that hole is a great shot makers hole. I kept punching a 3 iron on the shelf and running in on to a back pin locations. These four courses are right there with Crystal Downs as a comparison.
I would put Olympia, Hazeltine and Victoria on my next tier of favorites. All 3 were so difficult from the back tees. I liked Olympia probably a little better but I think had Victoria been in tip top shape it would have played a little nicer. Hazeltine is just golf. No tricks just length, thick rough, narrow and slick greens (can't go wrong with that). These courses were similar in my rankings to Oakland Hills, Arcadia Bluffs and Lakewood Shores - Gailes.
The next tier I would put Harvester, Greywalls, Wild Horse, Redlands Mesa and Lakota Canyon with Harvester and Greywalls being the best. I really think that The Harvester in Iowa is a top notch public in the U.S. Again, some of the bunkering style is not the norm (big round bowl bunkers) but the layout from hole to hole was terrific. #15 from the back tees is a beast, just to even walk all the way up the entire uphill par 5. Part of me likes Harvester enough to put it up with the next tier of courses. I would say that Redlands Mesa and Lakota are the lower 2 of this group. Great settings just I'm not huge on the manufactured Engh look. These courses were similar in my rankings to a Kingsley Club, Eagle Eye, Tanglewood Park.
Links of N.D., Old Works, Circling Raven, Hawktree and Quarry at Giants Ridge were probably the lower end of what I played. They weren't bad just were sort of "appetizer" courses as I call them (don't fill you up with golf but still taste good). I wasn't big on Quarry and Giants Ridge just in comparison to its rating from GD. I felt it was more of a top 40-60 not it's #16. Although, as I stated earlier, it had the most shot values. I really didn't like the way #17 and #18 were layed out though.
So there's some comparisons. Again, all of the courses are top courses.
If I had to make a dream 18 from what I played:
#1 @ Bandon Trails (par 4)
#4 @ Bandon Dunes (par 4)
#15 @ Prairie Dunes (par 3)
#3 @ Bandon Trails (par 5)
#5 @ Greywalls (par 4)
#16 @ Hazeltine (par 4)
#9 @ Lokota Canyon (Par 5)
#11 @ Pacific Dunes (par 3)
#9 @ Olympia (par 4)
#13 @ Pacific Dunes (par 4)
#13 @ Greywalls (par 5)
#16 @ Victoria (par 3)
#8 @ Prairie Dunes (par 4)
#14 @ Redlands Mesa (par 4)
#17 @ Harvester (par 3)
#8 @ Circling Raven (par 4)
#15 @ Harvester (par 5)
#16 @ Bandon Dunes (par 4)
