In Dubai, the market is more free and deregulated; Miami is also open, but with more controls and regulations (US federal laws apply). Regarding Bitcoin use, in Dubai, BTC is more common in everyday life for direct payments; in Miami, BTC is more commonly used as an investment. In my opinion, Dubai's weak point is the weather: too hot.
