I went with VectorStyle precisely because of the integration with Carrara (for example you can animate with Carrara physics and dump that to Flash). I also didn't feel like learning yet another 3D interface. I'm hopeful that there will be an upgrade to VectorStyle at some point to pick up the features that are new to v3. Discreet Plasma is another option in this space and will probably appeal to those who already know MAX. If you're into Flash, also check out swish at www.swishzone.com (I find it much easier to use than Macromedia Flash).
