Use what you have and avoid very much magnification or large scaling. It will translate better when you get to the real world. I doubt seriously if any of the sims are that realistic in 3D but can only comment on G2 as that is what I have flown on and Itallian Flyer is using. I know that G2 will do all of the above mentioned moves with the right plane except the flat spin.

Maybe AeroFly Pro or Super 3D Pilot Enhanced or some other sim is THE best but G2 is what most of us have to work with and there are a lot of cool downloadable planes and schemes for it.
