Away3D or Papervision3D?

I don’t really like to start these kind of threads, but lately I’ve been very confused.
I want to try my hand at 3D in Flash… I’ve noticed that Papervision and Away3d are very popular OS engines…

but which do you recommend? I don’t have any experience in 3D coding (but I do have experience with 3D apps).
Which one has the best power/speed/ease ratio?
