Usually, it is hard to imagine the difference in sensor sizes only by checking out a spec sheet. The picture below may provide you a clearer sense of the sensor sizes in the TG-860 and a3500.

As you can see, both the cameras posses different megapixels and different sensor sizes. The TG-860 with its smaller sensor is going to make shooting shallower depth of field harder and the Sony a3500 will provide greater detail having an extra 4MP. Greater resolution can also make it easier to crop images somewhat more aggressively. The more recent TG-860 should have a benefit with regard to sensor tech.
