FS2004 & X-Plane

Does anyone use both FS2004 and X-Plane

I do, and I'm amazed at the leaps & bounds X-Plane has made, it looks gourgeous nowadays. The main difference I think is that the physics are infinately better than FS, both in the aircraft and the environment. But it is overshadowed by Microsoft's comparatively brilliant built-in air traffic system and better scenery.

Just wondered what other people thought...?
