I flew reflex and g4 before getting FS One, and have to agree with Mike. I found with FSOne, if I could do the maneuvers there, I could do them in real life... after flying fsone for several months, when I fly other sims(and I fly others alot, I work at a LHS), I find them very easy, Which isn't necessarily what you want in a learning tool, unless you want your friends to think your cool because you can fly so good on the computer .
