I like the new course designs more than the average guy here, and like the old classics less than the average guy here. Generally, the two architects who receive the most praise here are Tom Doak and the team of Bill Coore and Ben Crenshaw. These guys build great golf courses, and it is my belief that these are the two best designers ever.
I'd say the most popular Golden Age architects here are MacKenzie, Ross, Flynn, and Raynor, with another dozen or so important guys who get slightly less attention: Colt, Allison, MacDonald, Behr, Thomas, and so on.
Several other prominent architects and designers contribute regularly to the site, some of whom are responsible for award winning designs. You'll get to know these guys if you stick around. Good guys, and an absolute treasure trove of knowledge.
Tom Fazio does not contribute, and his courses are quite controversial here. Some GCA members love them, and some dislike them. There is near universal (sometimes grudging) respect for both Fazio and Jack Nicklaus, the two most financially successful architects in the business.
That's a helluva top 10 list, Jordan. You are a lucky dog, you know that. Can you play?
