Blender's Compositing Nodes vs. Shake's (Which one is better/faster)

I know that Blender’s nodes can do alot, and is better for cheap people like me, but I can’t find any tutorials on how to use Blender’s nodes to composite into live video (with the camera moving). I have found many tuts on shake’s nodes. Is blender really better?

I just had a similar question.

There is a great tutorial there.
