- you are not really comparing sensors but jpeg engines

Technically it is both since the jpeg engine uses the output from the sensor. I purposefully used jpeg as 95% of the time I do not use RAW.

I think you are underestimating the impact of the jpg engine and the camera's high ISO NR algorithms to a final JPG.

You could have 2 sensors (lets call it Sensor A and Sensor B). Let's say "A" is theoretically 2 stops better high ISO performance then "B". If the jpg engine in "A" mushes the high ISO jpg and "B" does a better job the final jpg output will look better for B.

If you did the RAW processing yourself you'd find "A" 2 stops better.

If you use jpg 95% of the time then you really are evaluating the jpg engine IMO.  I've read many reviews here on cameras where the jpg engine destroys high ISO shots but the RAW files are completely acceptable.
