I vote for G3 physics are great the planes are a little snappy but if you learn your manuvers on G3 then the real thing seems easier. My wife spent about 2 months on G3 and I started her flying the real thing 3 weeks ago. Well within 1 week she had already flown her first solo flight not with a trainer but with my Harrier 3D 90! I would say that is not bad for a sim. Ypu also get the added advantage of flying online I learned to do rolling harriers coaching me online. That is its best quality I think. The only drawback I have seen is you need a fairly powerful pc to run it. I think its worth it!!
