I think if you have the G2 version it is a great 3D simulator if you r planes are set up properly.
The stock planes are garbage but with a lot of work I have come up with many good set-ups.
I set them up to simulate real world flight characteristics, not set up to fly easy, there is a difference.
I use it to practice all high alpha types of maneuvers.
It is not like being at the field but is real close to real flight characteristics.
All I can say is that it has helped my real world flying immensely.

I have not tried AFP but that looks good also.
