Often great music or literature can be difficult, or taxing to appreciate. Think Joyce or Miles Davis. But the appreciation is not a chore, and can come to become a thing of joy, life enriching, even. I know I don't always have the desire to read this kind of literature, often times I might rather read an aeroplane book, or listen to the Carpenters. Which isn't to say that the Carpenters aren't great..
Personally I like variety in my life. It's great to have one's game sternly tested from time to time. Occasionally it will hold up. It can also fun to hook up with some strangers who are playing from the forward tees.
I think that there are plenty of courses that are a stern test and also a joyful experience. I wouldn't include the Black Course or Carnoustie on the list, but Ganton, Dornoch, Maidstone..
