Which AS3 3D Engine do I use

lo all,

If anyone could give me some feedback. I’m currently pretty able with papervision but lately it’s been annoying me with things like texture overlap and pretty slow rendering.

I’ve heard good things briefly about away 3d, but can anyone vouch for alterniva or sandy (think I used sandy years ago in as2 and wasn’ too fussed)

Cheeras for any feedback anyone is able to give with this.
