I bought X-Plane 9 and I have FS9 as well as FSX. I HATED X-plane. I will stop myself from going on a rant why, but about the flight dynamics: It is documented that the aerodynamics in X-plane do NOT look at body interactions or other factors that alter each part of the aircraft's aerodynamics. Thus if you want to replicate a specific aircraft, the MSFS series is reputed to be better. They can claim X-plane has better flight dynamics because it actually calculates the forces, moments, drag, etc. You can actually turn on pressure plots and force vectors in X-plane to see it all around the plane...still I have many reasons why I hate it..but I will spare you.

EDIT: Microsoft Flight sims are FAA approved. My dad actually goes to Simuflight and Flight Safety for re-current in the Falcon 10, Lear 40/45, and Citation Bravo. At these facilities, they use a specialty version of MSFS for training. Graphics are identical! X-plane's FAA approved trainers are also highly specialized like the MSFS trainers.

Exactly jetprop! Accurate flight dynamics take a long long time to calculate. There is simply no way they are doing it accurately in real-time. There HAS to be a lot of give in the authenticity of the flight dynamics. What it does allow for though is better interaction between the aircraft and the weather as in crosswinds and turbulence. Still, I had such a horrid experience with X-Plane 9 I gave it away to the first class mate that asked about it!
