The only reason I can think of to live in the burbs, is that there can be better public schools, but if you are not raising a family, any argument you can give, I can give you a logical reason why living in a city is better.
Regardless of what you spend your money on, or chose to budget, living in a central location without needing a car, close to all amenities and services, is better, plain and simple. I don't see how that is not objective, unless you prefer living far removed from everything and wasting time out of your day traveling in a car, which statically the more time you spend driving the more likely you will die or be injured in a accident.
