Blasphemy!!

I think it comes down to a matter of personal taste. No pack is better or worse than another. Many people take the sounds they like from various packs and make their own personal one. I recommend trying them all.
Totally agree. It depends on what your hears like to hear. Some packs use external sounds (what the plane sounds like from outside). Others, like mine use internal sounds. Its all in the matter of what u like and how accurate you want it to be. Most of the american and the brit planes in mine are the real deal. There are a few others that do the same. Heck, some even use a harley engine as a plane engine, hehehe.
