I distrust the Golf Digest list because it is an effort to "scientifically" determine, through numbers, which golf couse is better than the next.
Each course is rated in 8 categories: Shot Values, Resistance to Scoring, Design Variety, Memorability, Aesthetics, Conditioning, Bonus Tradition, and Bonus Walking.
Each category seems to be on a scale from 1 to 10, except Bonus Walking, which appears to be 1 to 2.
The final score is calculated by adding up the scores in each individual category, with only the "Shot Values" score counting twice.
So Golf Digest says that conditioning and aesthetics are exactly as important as each other, and are exactly as important as memorability, design variety, and resistance to scoring.
I would argue that these ratios differ from person to person. I naturally prefer a better-conditioned course to a lesser-conditioned course. But when I played Princeville, and the greens were in lousy shape, I didn't include that in my appraisal that the coure was "fabulous".
The numbers are a tool that the editors get to hide behind. Instead of presenting this as a subjective list, which it is, they can say, "Hey, this is how the numbers stacked up, with no tinkering on our part. This is purely objective."
It isn't objective.
