I agree that Blender is already a 500 Lbs gorilla. Blender 3.0 will without a doubt be the 800 Lbs gorilla. It will be a smash hit and it will take no prisoners.

I recently downloaded Blender 2.68 and played with it for a couple of hours. I can already tell you, and that may come as a surprise, that I really like the interface.

Blender's UI is certainly far better than Lightwave', a lot less confusing than Modo's, and probably as good as C4D's. I personally feel very comfortable with it.

But Carrara's superiority over Blender is its vast library of pre-made contents. Creating a Blender scene with animated characters and believable lip syncs is most likely an involved process, while with Carrara it's quite simple. Although I have no doubt that Blender is a lot better than Carrara for complex animations and interactions between characters, based on the few made-with-Blender movies that I have seen on YouTube.
