RND is absolutely one of favourite golf places, and golf clubs, in the world. Its closest UK parallel in terms of club and course ambience is probably RStD Harlech, an historic club that was similarly once much more 'officer-class' than it is now. Both also had numerous associations with (public) school masters, as reflected in RND's Schoolmasters Cup.
In terms of course comparisons, I would suggest that perhaps the strongest parallel to TOC within Devon is actually Dawlish Warren (an eccentric nomination, I know, but topographically justified!) rather than the Ho! itself. It's now more than a decade since my last trip to RND, something I hope very much to rectify once COVID permits. Ran's (brilliant) piece on RND, read in tandem with Patric Dickinson (likewise), should encourage as many GCA followers as possible to make the pilgrimage to Westward Ho!, and they won't be disappointed, either by the golf course or the clubhouse.
As a PS, there is, as is appropriate, a good deal of RND coverage in the fab new Fowler biography discussed elsewhere on GCA
