The asynchronous option allows you to report progress and utilize your data immediately and do with it whatever you wish while the synchronous option requires you wait until the entire data has been retrieved, possibly an issue if you have data of any size. Also, for UI responsiveness, the synchronous option really only makes sense on a secondary thread while the asynchronous option can be fully performed on the main thread.
