actionscript 3 - Which 3D flash physics engine is better and why? -

My list has open-source and both dynamic demos and I want to know what is different and which engines are better Do you have any experience with any of these? Do you know the professionals and the opposition while working with these physics engineers?

I will recommend jiglibflash works with Jigilib Flash AVI 3D and Flash 11 Beta. After coming out of Flash 11 beta, you will be able to use a lower level GPU API. Install Beta and View Demo

I have not used the WOW engine, but it seems that it is not being actively developed because there was no update for about one year.
