Fly Tampa, Flight Beam and FSDT are the best sceneries out there. I fly commercial airplanes on the sim so I can't speak for sceneries of airfields. I don't get sceneries from aerosoft anymore because they are SO frame rate heavy. It's ashame because they have airporys I really want to fly in but it's impossible to fly with those FPS. I have an extremely powerful computer that was made by a company that builds computers for FSX so it runs all other other types of addons without difficulty.
In conclusion, I advise against aerosoft airports because they kill frame rates. I highly recommend the three I mentioned earlier; the only fsdt airport I have difficulty with on fps is ft lauderdale.
One more thing. If you fly PMDG airplanes then aerosoft is not a good idea. Captain can will do better in those sceneries but the poor fps is still noticeable. It will be bad fps unless your flying a default airplane.
