If you think Realflight feels more "real" than you would be in the minority. The giant scale airplanes on RF are pigs and unrealistic. You don't have to go any further than doing knifeedge with the Yak to see it flies like an arcade game. AF has a much better feel, especially doing 3d.

And yes I own them all except the latest RF. In my opinion RF wouldn't be as popular if it wasn't mainstreamed by Tower. Its no different than people that argue that Bose make the best speakers. It's all from a marketing perspective.
