Flash 10 3d or Papervision?

What do you think? Done with Papervision or just using the new Flash player 10 3d?

It would be more practical to have made it via 10's 3D. A simple transition stuff using a little y and x rotation manipulation.

Could have been done in papervision.

I did some CPU testing on how it handles it, and I'd say it was 10's 3D.
