Is it unfair to compare large cities with small cities?
Each city has its advantages and disadvantages. It depends on their economic and social environment, healthcare and educational programs, recreation and transport infrastructure. Some cities situated in fabulous places, where a lot of healthy food and sun, but there are not good schools and universities for education. Another cities have perfect conditions for career and business, but they suffer because of pollution, traffic and high crime rates.
So, I think, it isnít unfair to compare large cities with small ones. They just need to be evaluated by various criteria that everybody could understand what the best city to him to live in.
