Which one out of these three cities do you think is the best in the world? I know each city has something unique to offer, but still we do have some opinions about what a best city should have. I would appreciate if you tell me why you like a particular city among these three.

New York City is considered like a dreamland by many people where they can find lots of opportunities and have people from different parts of the world. It is considered as the financial capital of the world by many people and is also quite famous as a fashion capital. There is always something going on in this city. People also call it the city that never sleeps.

London is another multicultural city which has its own attractions like Big Ben, London Eye, Harrods, Thames river, huge public parks which are better than New York's central park. It has lots of museums. Being closer to other European countries has its own advantage and British people can go out of the country for a short vacation easily. It is also considered as a fashion hub and one of the largest financial centres.

Sydney is one of the best cities in the world. Many people call it London on Caribbean. It has beaches, lots of entertainment, I guess someone on gags told me that prostitution is legal too. There's a red light district. It is another multicultural city just like New York and London.

PS: I am going to ask more questions based on cities comparison. If you have any suggestions to improve my questions then please let me know. I hope I can make it more interesting in future questions.
