I always liked courses with lots of eye candy, great elevation changes, forced carries, creative bunkering. This does not mean that I think they are better, they just get my heart beating faster. Examples are the 8th hole at Pebble Beach, 16th hole at Cypress, 17th hole at Sawgrass, 4th hole at Pine Valley, etc.
I remember playing a course badly, missing a bunch of greens but chipping and putting great. I added up my score at the end of the round and it was 70, even par on that course. I just shook my head, remembering later that it was a bad round of golf, but had I played one of those above, my reaction would be entirely different
