Sometimes, it can be difficult to visualise the gap in sensor dimensions merely by going through technical specs. The image below may give you a better sense of the sensor sizing in the E-M1 II and A6300.

As you can tell, each of these cameras have got different resolutions and different sensor dimensions. The E-M1 II because of its smaller sensor will make achieving shallow depth of field trickier and the Sony A6300 will provide more detail having its extra 4MP. Higher resolution will allow you to crop photographs much more aggressively. The younger E-M1 II is going to have an advantage in sensor technology.
