As you can see, each of these cameras posses different megapixels and different sensor sizing. The CX3 because of its smaller sensor is going to make getting shallow depth of field tougher and the Ricoh CX3 will provide extra detail due to its extra 5 Megapixels. Higher resolution will allow you to crop shots somewhat more aggressively. The newer CX3 should have an edge with regard to sensor innovation.
