I've only played with G2 at the hobby shop, and owned Realflight Deluxe for years, but after using Aerofly Pro for the last month I can say that Aerofly Pro's is as good or better than the others. The slow speed flight is just like flying at the field. If you are shooting for low price, make sure the one you buy has the ability to add planes. There are free planes for Aerofly Pro available at some of the sites mentioned in other posts. My favorite is the Katana.
