I am looking to buy one of AFP or G3 simulator.
Are they closer to real life them FMS?

I have FMS 2.85 installed on my computer and find that out of about 100 planes that I have I like 2-3.
But even they are far from being close to real RC planes.
I am learning 3D type of maneuvers. On FMS some are too easy to perform, that I can hardly perform in real life, and some are impossible to do in FMS, but I can almost do them with real RC plane. And it all depends on what 3D plane I choose in FMS.
I am really would like to know if buy one the commercial simulators (AFP) will help me to learn to perform aerobatic and 3D.

Thanks in advance,
Pashka.

PS
Just to explain my skills:
I have been flying for a while. I am not novice, nor a expert - kind of intermediate.
I am flying right now OMP profile Extra 300, Yak 54F, UCD 3D EPP and some others.
