I'm with Sean on thinking Princes is a fair bit better course than one might think from its lack of esteem on this forum. I suspect if it were tucked away 50 miles from any other decent links courses it might be considered a hidden gem. Being adjacent to Sandwich and close to Deal would make most courses seem a bit lackluster by comparison.
More generally speaking, I think it's not cool around here to like courses that "Don't take advantage of the dunes" often shortened to "flat". I truly enjoyed my day at Royal Birkdale for instance and think it's about as well-sorted, highly refined a championship course as one could ever hope to see. The fact that there are large-ish dunes on the property that do not have tee boxes or greens atop them does nothing to make the actual playing value of the course less than outstanding IMO.
There are probably other "flat" courses with fine turf, plenty of small-scale undulation and sufficient contour in play to provide a wonderful short-game experience that are none the less downgraded for not having numerous uphill, downhill or sidehill shots to be played.
