WebGL vs Silverlight vs Flash MoleHill

Hey guys. I’m trying to create a Web Banner using the latest technology of 3D graphics? Which ones do you guys think is a good one to use?

Or do you think its even worth creating anything with any 3D API’s because its still so immature?

If you’re going to use 3d the most viable option currently is to use flash molehill, purely because it has a far wider reach than webGL. If your banner is going to be propagated via any of the common ad networks then check the specification because chances are the filesize allowed and flash version may hinder what you are trying to do.
