Do a search on "simulators" in this forum... you'll find LOTS of information.

Any simulator is better than no simulator. they all can help with learning the control reversal due to the airplane comming toward yourself.

Some are better than others at the physics modeling...

Its fairly hard to stall a model in the RipMax simulator. But when you crash it leaves a debris field appropriate to the impact. (playing with how far you can spread the pieces can be entertaining... )

FMS has better physics... but not as good graphics as even the RipMax sim.

Real Flight has one of the best flight physics engines and the best graphics.... you pay quite a bit for it.

Microsoft Flight Simulator, from Tower view is not a bad RC simulator. Good flight physics (especially the newer version) excelent graphics and 1000's of airplane profiles for free DL all over the internet.
