Before we go into a more detailed comparison, here is a simple synopsis of how the SZ-10 grades vs the A7 III with respect to portability, imaging, features and an overall mark.

Normally, its difficult to visualise the contrast in sensor dimensions only by viewing specs. The image here should give you a more clear sense of the sensor sizing in the SZ-10 and A7 III.

As you can plainly see, the two cameras have different megapixel count and different sensor dimensions. The SZ-10 featuring a smaller sensor will make getting shallower DOF harder and the Sony A7 III will provide you with more detail as a result of its extra 10MP. Greater resolution can also help you crop photos a bit more aggressively. The more aged SZ-10 will be disadvantaged in sensor innovation.
