LOL! Now I see where your problem mainly lies.
Part of it's your assuming. "People" call 3D CG, CG because that's what they 'generally' associate it with. Anime fans have known for a while now that most anime is done on computer.
But your main issue is Human made vs Computer made(generated). The designs are ALL Human made, thus ALL of the CG is Human made, but generated on the Computer. The Computer's don't make anything except what they are told to make.
Save your brain and consider the computer as today's pencil. Well until Singularity hits then we're all screwed!
*facepalm*
3D cg vs 2D hand generated. You can not compare mechanical 3D vs mechanical 2D. One is technical 'perfect' everytime vs one that 'perfect' from an artistic viewpoint.
*sigh* (gods i hate that stupid kindergarden debate)
Choreography is the ONLY viable way to compare, and then that's full on subjective. IMO.
You should go watch Moonlight Mile.
