One of the developers of the Flight Simulator team released a new screenshot which compares a scene in the game in DX9 and DX10 mode.
As you can see on the picture the difference between DX9 and DX10 is pretty big but to be honest I'm not sure which picture looks best or most realistic. More info at PTaylor's blog. He also claims the DX10 version features several performance improvements which will increase the FPS by up to 20% under load.
