I'm also an enthusiast of the micro$oft FS, and my choice is the A320 Professional add-on, after a long search about the best choice for a sim plane.
But if flying one of the most (?!) accurate sim planes is compared to driving a Porsche in a sim and in real life, as I actually did I confess
, then flying in a sim lacks all those forces surrounding, the noise, the shaking, the wind effects, that give us the feedback to auto adjust to the situation and perfect the eye-hand response.
As I can't drive a sim car better than a 8yr old
, I suppose that all the countless hours I've spent behind the joystick won't get me close to the real feeling of flying, and the real aircraft behaviour, although we can have a very good idea of the procedures (incomplete I know) involved.
