As you can see, both of these cameras come with different megapixel count and different sensor measurements. The S1R with its larger sensor is going to make shooting shallow depth of field less difficult and the Panasonic S1R will result in more detail with its extra 31 Megapixels. Greater resolution can also let you crop pics a good deal more aggressively. The fresher S1R should have a benefit in sensor technology.
