These are all extremely different cities. Where do your interests lie? What do you care about? If financial opportunity is at the top, NYC and SF win by a long shot. If public transit is important to you, Chicago is miles ahead of the rest. If vacation lifestyle is most important, that goes without saying- Miami. Way too many moving parts to rely on a poll my guy.
My advice is to get a PhD in physics so you can build a model that recommends which city lies in your best interest.
