From a sociological perspective, you won’t find a more interesting city to study. I can see this argument. There are certainly enough interesting sociological issues in San Francisco regardless of whether you think it deserves the "most" qualifier. San Francisco has the prettiest natural surroundings of any city in America. I think this one is very hard to argue. It's highly subjective, so I don't doubt that the author believes it, but if someone were asking me where to move and told me that they prioritize beautiful surroundings, San Francisco wouldn't make my list of recommendations.
