That depends on what aspects of it you find "poor and inaccurate." X-Plane has thousands of airports in the sim but many of them have never been improved from their "default" form of runways & extremely basic taxiways. You can check airports here on the Gateway to see if an artist has improved them or not (WEDbot as the artist indicates it is only the default, unimproved scenery).
Otherwise, X-Plane uses Open Street Map data to place roads, autogen buildings, and more. If this data is inaccurate, it leads to inaccuracies in the sim as well.
