As you have seen, both of these cameras have got different megapixel count and different sensor sizing. The Quattro H because of its larger sensor is going to make achieving shallower depth of field easier and the Sigma Quattro H will provide more detail as a result of its extra 21MP. Greater resolution will allow you to crop images much more aggressively. The older Quattro H will be disadvantaged in sensor innovation.
