The two courses are fundamentally different, first by age, then by development, ownership and design. The concept of the Old Course has no parallel with North Berwick due to the slow development of the course from a selection of holes which increased then finally reduce to the now standard of 18 holes. NB was effective new from 1830's with just a half a dozen holes, although some golf may have been played on the small links from the late 1700's.
Both courses produce that fun factor and challenge, with the Old Course being developed (in part) in the 19th Century with the average player in mind.
Also today we have the Public Course vs. Club Course and the needs of each town with St Andrews remaining the dominate influence on golf from the start, even overriding other early golf sites.
Love both courses and they give more than just fun & delight, however
I would accept the 18th on both may appear similar, but IMHO they are not – TOC 357 (4) & NB 278 (4). Plus what about that inner feeling which
is generated when walking up to the 18th Green at St Andrews. Is it not a thrill every time?
My opinion is that we should not try and compare them, just play and
enjoy the experience, again & again & again & again & again & again & again – is it not the reason why we play golf?
