it quite different from my experience, I was using myeclipse + flex plugin. I remember that myeclipse hangs every 20 minutes, and that happen not only on my PC, that happen to all my teammates PC, while developing Flex, and it work OK when we're developing java backend.

I'm no fan of Eclipse. I've never used myeclipse, so I can't speak to that. I've used Flash Builder (in a mostly stock way) with varied levels of success. IntelliJ has really nice Flex tooling though.
