hey,

simple game, pick the image you like better based on IQ and high ISO results! after 15 guesses, i'll reveal which images belongs to each camera.

Now you got me as well there until you revealed the truth. 

The difference between the sensor efficiency isn't all that great, which leaves much to proper noise treatment.

Here is a 100% crop comparison of 30D and 6D at iso 3200. Both shot at 1/60s f1.8 ISO 3200, handheld. Both treated with the normal curve, no sharpening, no NR,  2700K.

(use view original for 100%)

The biggest difference is that the 6D nailed the focus on the target bush, while the 30D found the brighter lit background. You can also see that there are quite a few pixels going hot on the 30D, while the 6D is pretty clean. Colour noise isn't all that much different.

Now this jpg is of course not revealing every difference that there are, only that much of the overall IQ difference between these come from sensor size, and the availability of higher ISOs.
