Cities rated: Tokyo best globally; Austin preferred for living

Hong Kong was described as the saddest world city due to its political situation: "Sadly, Hong Kong is a place I watch slide from the perch on which I used to hold it as it turns to the mainland." The greatest flawed city was named New York due to its high cost of living but significant opportunities in various industries.

Austin emerged as the city where the author most wants to live. They currently reside there after moving from Washington D.C., citing better livability despite some issues such as high real estate prices and summer heat.

New York City received criticism for being poorly managed but remains attractive due to its concentration of exceptional people across various industries. "New York is badly run... And yet it brings together large numbers of exceptional and ambitious people."

Los Angeles was recognized for its ethnic food offerings despite high living costs. Falls Church also received mention for its culinary scene with specific recommendations like Elephant Jumps for Thai cuisine.

Singapore's reputation suffers from perceptions of sterility but is lauded for its excellent management and diverse food options at both high-end and street levels. Tokyo's density and excitement were also highlighted alongside its culinary diversity.

Vienna holds sentimental value but is not seen as an ideal place to live permanently. Toronto was suggested as one of the world's most underrated cities despite cold weather conditions, while Vancouver also received praise.

Amsterdam's appeal fluctuates with tourist seasons; it's considered fantastic when less crowded. Austin’s popularity has grown over time with increasing housing prices but remains valued by residents like the author who appreciate good barbecue and cultural activities.

The evaluation concludes by noting that preferences for great cities vary individually based on factors such as food quality, weather conditions, taxes, regulation impacts on business opportunities or job prospects, and energy supply concerns in places like Texas.

Ultimately no single place is perfect; what makes a great city depends significantly on personal priorities and lifestyle choices.
