Typically, it is very difficult to imagine the contrast between sensor sizes just by reading technical specs. The image here might provide you a better sense of the sensor sizing in the E-PL7 and ZS20.

As you can tell, each of the cameras offer different megapixels and different sensor sizes. The E-PL7 because of its larger sensor is going to make shooting shallower DOF simpler and the Olympus E-PL7 will offer more detail due to its extra 2 Megapixels. Greater resolution will also enable you to crop pics a little more aggressively. The newer E-PL7 should have a benefit in sensor tech.
