Twisted and Gevent are two other asynchronous frameworks that are very famous. However, since its release in Python 3.4, AsyncIO has become very popular rather quickly. There is no doubt that one reason for this success comes from the philosophy of Python: There should be only one obvious way to do something. Since AsyncIO is part of the standard library, it is the de facto  way to do asynchronous programming in Python. Another reason is probably that it was released with the correct timing, when developers regained interest in asynchronous programming.
