Which 3D flash physics engine is better and why?

I have on my list the open-source wow-engine and Jiglibflash. Both have impressive demos and I'd like to know what's different and which engine is b开发者_运维百科etter. Do you have any experience with any of these? Do you know the pros and cons when working with these physics engines?

I would recommend jiglibflash. JiglibFlash works with Away3d and the Flash 11 beta. Once Flash 11 comes out of Beta you'll be able to use the low-level GPU APIs. Install the beta and check out the demos at http://www.jiglibflash.com/blog/2011/02/27/jiglibflashfp11/

I haven't used the WOW Engine, but it looks like it is not being developed actively, as it had no updates for almost a year.
