I agree with bobs on this one. The throttle respone is the biggest difference. I believe the sim is a lot different than the "real world" flying. The greatest part about the sim for beginners is it teaches you not to over-control the airplane and helps you understand the backwards control when the plane is flying toward you. This is its biggest benefit. I think in some aspects its much easier to fly for real than on the sim. You have a much better perspective when flying at the field. When you fly on the sim its almost like you have "blinders" on.

If you are learning to fly I highly recomend it. It will shorten your learning time dramatically and may save you a few planes.

Happy Flying!!!!
