Flash had its problems but as a user, it looked sharper and smoother than even current websites. And its editor gave non-tech users ability to create amazing animations, interfaces, and even games.

wasn't some of that smoothness because it ran at a 100hz tick without any way of adapting it (and still running existing code)? That was the complaint I kept hearing from people attempting to make flash on phones viable (this led to ludicrous battery consumption)

Image-wise, SVGA + JS probably gets you the clarity. Standard gif / image animations not so much, if that's what you're referencing.

This isn't my baliwick, so I've absolutely nothing to say about the ease with which these options can be created.
