Well, in adobe flash you have a stage where you can put instances, draw objects and you have time line to put some animations, and with flash develop(I think you need adobe flash or adobe flex to use it)you dont have a stage to draw object but have a really good organized library where you can make classes easily and it shows you the real concept of programming, maybe make games in flash develop is more complex but I think that it shows you how to work with real programming IDEs, anyways if you are a beginner I sugest you to use adobe flash :3
ya but that is tooo much money... i got flashdevlop... lol and it looks good... i also watched a tutorial so i know how to use it(very little) but i still dont no any hardcore code...
