The lack of blotchiness in the noise, and the apparent randomness of it. It really does remind me of film and should clean up REALLY well.

Blotchiness is usually due in Canons to subliminal banding noise - banding strong enough to group together random 2D chromatic noise of the same color as the band from neighboring lines of the same color (blue-green or red-green, and the green is usually low because most WB settings only boost red and/or blue).

So, when you get less banding, you get less blotchiness. Canon has passively sabotaged many of their existing cameras, by not reducing banding noise (easily done post-capture if the sensor is designed for it).
