A more fair comparison would be from a raw converter where we can know it does the same processing for both cameras (preferably with no NR). For some reason commercial raw converters do their best to hide what they do from the user.
You can use dcraw if you want to trust that it doesn't to anything more than you ask for. (Or you can make the raw files available so someone else can do that.)
Later this week I will zip up the raw files and post them on a file share site for download.
