This question was made over 9 years ago. It made sense then, it doesn\'t make it now. Flash is hard on its way out; sup
My understanding is that the big deal about the tag is that it is an open standard. When only one vendor can implement Flash, you are at their mercy for implementations/ports to new platforms, browsers, or even browser versions.
The excitement is all at that level, not down in the implementation details. Worrying about which is technically superior is sort of beside the point in the same way as concerning yourself about a fascist government's ability to make the trains run on time would be.
