Plainly, each of the cameras feature different megapixels and different sensor sizes. The X70 with its tinier sensor is going to make shooting shallow depth of field more challenging and the Sony A6100 will give greater detail having an extra 12 Megapixels. Higher resolution can also allow you to crop pictures way more aggressively. The more aged X70 is going to be disadvantaged when it comes to sensor tech.
