I find it funny how easily folks can make empirical statements on how one sim is better than another when it is such a subjective experience.

I have flown RC for 30 years and used Realflight for quite some time to practice and experiment.

I helped behind the counter of a local hobby shop over the Christmas holiday where both FS One and RF G3.5 were available to try and buy.

I personally didn't like the feel of many of the planes in FS One and the controller seemed to have weak springs on the gimbals.

I am not going to tell you that since I prefer G3 that you should go that way. Rather look at and try both of these sims if not AFPD also.

Then decide for yourself.
