Best city between these two?

Which is the best city between these two....Miami,Fl. or Atlanta, Ga. ? Important considerations are :jobs, weather, audio shopping :), good shopping for the lady, and the arts and alot to do. My fiance has lived in some big cities(London,U.K.,Paris, France) and wants to live in a similar type of city. Anyone who lives in either of these cities now or ever, could you recommend nice areas and opinions? Thanks in advance.
