Our team is using IntelliJ for AIR/Flex development since 4 years now and we are really happy with it. Its fast, reliable and offers a bunch of useful features. Haven't worked with Moonshine or VSCode yet but heard they are also quite good. I would think the bigger and more complex your project is, the more would IntelliJ be the right choice.
