How many HTTP requests do you need to have this running? What is the overall size of files and their synchronization? How easy is it for you to change something or add something a week after the animation is done and released? How long does it take to create the animation in general? Do you need complex battery draining animation on your unplugged device?
Most of those answers would be in favor of flash, which is on (as stated in comments above) most computers worldwide. ROI (or value, you get for your time spent on a project) for HTML5/CSS3 is very bad and makes it possible only for some very easy non-reusable tasks and animations.
