As you can plainly see, both of the cameras provide different megapixels and different sensor dimensions. The E-P1 having a tinier sensor will make getting shallower DOF trickier and the Pentax K-1 II will give more detail because of its extra 24MP. Higher resolution will make it easier to crop pictures more aggressively. The more aged E-P1 is going to be disadvantaged with regard to sensor tech.
