Well I guess there is the answer, RF is best! In the last 10-15 years ,Accu Rc - Next and Heli X have become the go to RC Heli programs. As for airplanes Realflight is a strong contender. My first simulator was a Dave Brown around 1991 , when RF deluxe came out in 1995 it was a game changer. I have bought most of the updated versions including the disaster, Reaflight X. I currently have Realflight Evo and it is good for the planes and the helis are ok, but for me Heli X is the go to heli sim and many of the other heli flyers I know us it also. Go to a real heli forum and ask this question, you will get better feedback. This is all personal opinion and I would never tell you which is best, this is just my opinion after using them all. They all work great as long as you put in the time on them. Good luck and have fun.
