Clearly, each of these cameras have got different megapixel count and different sensor sizes. The E-M5 having a tinier sensor is going to make shooting shallower DOF more challenging and the Panasonic S1 will give extra detail because of its extra 8MP. Higher resolution can also let you crop pictures much more aggressively. The more aged E-M5 is going to be behind in sensor technology.
