KClarke;
Honestly, for me that's sort of a hard question to answer. Both of them but including Hanse & Co and maybe DeVries and possibly Echenrode and kelly Moran, Rod Whitman, looks like Tony Ristola, seem to be way out in the forefront in creating really natural architecture in every way, if you know what I mean.
All their features (particularly the bunkering), all their architectural "lines" seem to be so far out in front of everyone else today in doing architecture that looks like some of the greatest of the Golden Age in its overall naturalness and strategic design.
Most all of them seem to be building some really wonderful greens too--in shape, dimension, internal contours, playabilities etc that are not in the slightest man-made contrived looking--that fit right into the pre-construction landscape etc!
Obviously, this group's courses probably need more time in play to prove themselves but honestly the look of most all of them are neck and neck with the best of the "Golden Age", if not even surpassing them, if you ask me.
The thought through natural and strategic detail in courses like Pacific Dunes, I hear Lubbock, looks like Stonewall 2, Friar's Head, Hidden Creek, Easthampton, Cusgowilla, Rustic Canyon, Applebrook, Inniscrone, Tallgrass, U of Alabama, French Creek, Barona, looks like Tony Ristola's course in Germany and some of the others I've only heard about seems really impressive.
One of the differences possibly between Doak and Coore, is it seems like C&C have done a course or two as semi tributes to another style, era or look like Hidden Creek is basically a tribute to the Heathland style.
I'm not sure Tom Doak has done anything like that. Not that it's important to do, I just don't know that he's ever done that--seems like Doak's courses are just site unique. But who knows; I've always heard the 3rd green at Stonewall1 is a pretty good copy of Crystal Downs #1 green. It has to be--both greens are very similar.
There really is some terrific architecture coming from this group recently, and now look what Doak has going in New Zealand. And the Coore and Crenshaw company seem to be pretty high on the possiblities of the course under construction in Plymouth Mass. The good news there is almost all their guys are up there working as it's the only course they're working on right now. Gil Hanse will be starting soon in Mass too.
