Anything that is labeled as Macromedia Flash is an older version of Flash, created when Macromedia, the original producer of the software still existed. This applies up thru Flash version 8.
Macromedia products were bought out / taken over by Adobe after version 8. Anything that does not include the name Macromedia, such as Flash CS3 and CS4, was produced by Adobe.
Flash CS4 would be considered better because it is newer and has newer features, though in this world you can never be sure, newer doesn't always mean better.
CS4 is much more powerful. It can do something like pivot, but with images. It can also make 3D animations, make motion tweens easier to make etc. And CS4 is also much more expensive, but it is hard to find flash 8 or older versions.
And you can also use a spray tool which can spray things. Look at this page:
