I can't imagine being able to complete an animated banner ad implemented in HTML5/JS (or Flex for that matter) in anywhere close to the time it would take within the Flash IDE. Using the Flash IDE, I can also apply JPEG compression to 24-bit PNGs (with alpha channels). I really wish there was a similar alternative for HTML. And as poor/buggy as the font support is in Flash, it's still far better than using a flattened image. The timeline, filter effects and third party tweening solutions also bring a lot to the table.
