The E90 featuring a smaller sensor is going to make getting shallower depth of field more difficult and the Sony A7 II will show more detail having its extra 14MP. Greater resolution can also help you crop pics a little more aggressively. The older E90 will be disadvantaged with regard to sensor technology.
