The balloon popping was in reference to another sim

Steve, It would be pretty irresponsible of me to answer that as I have never had the pleasure of flying IMAC. I could tell you which one I "think" is more accurate for that but that would be opinion only. The fact is there are two different users of simulators: The new to the hobby users who want to learn how not to crash a plane, and expirienced pilots who want to polish their skills. All the sims are great for the first. However for the latter I would say you need to do everything in your power to try each of the big 3 before buying. NONE of the sims are absolutely aerodynamically perfect (fact!). What may feel close for one may feel off to another. The worst thing to do is to put out the question "which one do I buy guys". most people will say to buy the one they have so they can justify spending 200 dollars on it (human nature). You wouldn't buy a car ONLY based on what a few people in a chat forum say about it.
The fact is, all 3 sims are great training tools. They all have "good" aerodynamics engines for the small price tags (the military and nasa have aerodynamics simulation worth millions that aren't perfect). You really need to try them all. The best thing to do is really study the flight parameters for the specific sim you are using and "tweak" them until they do feel perfect (for you). But for anyone to answer that ol question by saying "this one is the BEST" is pretty silly, but not as silly as the person who buys a sim based on that statement. so I won't do that.
