I respectfully, partially, disagree - the simulators I have used vary so much in their manual flight characteristics that they are almost incomparable. I'm finding them harder to fly of late, though it could be any factor (or combination) of age, increase in experience of the real aircraft, poorer quality simulation (these are not the most expensive models available) or wear and tear on the sims themselves. I fly a fair bit manually, liking to practice raw IFR and plenty of visual approaches and circuits, so am not especially rusty at hand flying. But I am finding more and more that sims are ok at procedural training but hopeless for handling training.
