"Another subjective post".
What a sniffy thing to say Joel! 99.9% of what appears on here is subjective - including Ran's write-up that you approvingly quote - but happy to hear if you have discovered some objective standard you wish to share! Repeating the opinion of a distinguished golf author, comparing two memorable holes, is hardly the stuff of controversy.
Josh - there is no question on my part, just passing on the opinion, which appears in the Addington's centenary brochure. For what it is worth, they are both memorable holes in an uplifting sort of a way - as in, they stay in the memory, and you know that only a great shot will suffice - and that is probably a pretty good approximation of "greatness", and a standard that only a very few holes meet.
Incidentally, I think one way of capturing the difference is that while 3 is a difficult score on both holes, a reasonable golfer should be able to make bogey at Addington most times - not so Pine Valley, because even if you miss the green and recover, you still have an excellent chance of three-putting no matter how close you are to the flag.
