Personally I'd have thought the best way to check IQ of a camera against other cameras if you were concerned about ISO would be to shoot the same scene with both cameras with the same shutter speed, ISO and aperture and have a look at the resulting photos. Maybe I'm a bit old school that way.

That's close, but there is one more step. If one of the photos is darker than the other, you need to brighten it on the computer so that they match.
