As you can see, each of the cameras provide different megapixels and different sensor sizing. The PX due to its tinier sensor is going to make getting shallower depth of field more challenging and the Ricoh PX will give you greater detail due to its extra 2 Megapixels. Greater resolution will also make it easier to crop images more aggressively. The more recent PX provides an advantage in sensor innovation.
