Allow me to pile on top of jkinney's comments:
Although I enjoyed Rock Creek immensely, I felt that Stone Eagle and Rock Creek were about equal.
1. Both have 4 par 3s, 3 of which are distinctly downhill. #13 at Rock Creek stands out as the lone uphill 3, and may be the best of the bunch, but #12 at Rock Creek may be the least interesting.
2. Both have 3 par 5s. Let's call them equal. All six are good holes, reachable with two excellent shots, but filled with enough trouble to make double.
3. The par 4s at Stone Eagle are its weakness, since the property dictated they all be routed up and down the hill. #9 and #11, and even #16 are substantially similar, steeply down and to the left. #9 is a wonderful hole, and all three have approach shots which are delightful to watch.
Rock Creek's par 4s have great variety, with a few showstoppers, like #4, #7, #11, #14, and #16. Great par 4s.
4. Both course are very hilly, though Rock Creek is a better walking course. It still makes for a long round when you walk Rock Creek. Most foursomes will take 4.5 hours or more. If Stone Eagle had bridges over the ravine on #13 and #14 like that beautiful bridge on Rock Creek #13, I'd walk it occasionally. The bottom line is not many will walk either course, so what's the difference?
5. Rock Creek has a worse "lost ball" problem. Far more balls end up in the junk, and it's harder to find when you're in it. Stone Eagle's connecting fairways save quite a few errant tee balls.
6. Each course has its share of blind shots, but Rock Creek does not give the player the satisfaction of watching his shots land and come to rest enough. You get to watch your shots finish at Stone Eagle much more often.
7. I say Stone Eagle is significantly more beautiful, though that is purely subjective. Stone Eagle is the most beautiful piece of golf art I have ever seen. Short range views everywhere, and long range views on the back nine. Phenomenal beauty.
8. Rock Creek is a bit harder, but both are medium difficult. I played like shit in the Renaissance Cup rounds in the morning, then tore it up in the afternoon when it didn't matter.
9. Finally, I find the two courses very similar in most ways. Types of challenges, conditioning, green speeds, everything. Stone Eagle came first and Rock Creek followed similarly in its footsteps.
Consider this a challenge to anyone who would like to argue why Rock Creek is significantly better.
