The 77D was announced 8 years later than the E-420 and that is quite a serious gap as far as technology is concerned. The two cameras offer different body type with the Canon 77D being a Mid-size SLR camera and the Olympus E-420 being a Compact SLR camera.

Before getting straight into a thorough comparison, below is a short synopsis of how the 77D matches up vs the E-420 with regard to portability, imaging, features and an overall grade.

This is a sample of the gallery pictures for Canon EOS 77D and Olympus E-420. The whole galleries are viewable at Canon 77D Gallery and Olympus E-420 Gallery.

If you're going to lug around your camera, you need to factor in its weight and proportions.

Take into consideration, the weight of an Interchangeable Lens Camera will differ depending on the lens you choose at the time. Following is the front view over all size comparison of the 77D and the E-420.

Factoring in dimensions and weight, the portability grade of the 77D and E-420 is 66 and 77 respectively.

Typically, it is very tough to imagine the difference between sensor measurements only by going over technical specs. The photograph below will help give you a stronger sense of the sensor measurements in the 77D and E-420.

As you have seen, the two cameras offer different resolutions and different sensor measurements. The 77D using its larger sensor is going to make getting shallower depth of field less difficult and the Canon 77D will offer more detail with its extra 14 Megapixels. Greater resolution can also make it easier to crop images a little more aggressively. The newer 77D provides a benefit in sensor technology.
