Sorry to break up your little circle-jerk here, but if you really need to bring security holes into the discussion you have lost already. You understand the the type of security holes that are found in the Flash player to not concern the average gamedev, right?
And all the AS3 core functionality runs pretty solid, please show me these mayor bugs you talk about. I've also been a game dev for many years and started out at Flash before finding my place with one of the bigger studios. I still use Flash regularly to bounce ideas around and I still love it. If you really run into that many issues with Flash these are probably performance related and you should probably move on to a higher level language because you have outgrown the AS3 api.
