Quite often, it's hard to visualise the gap between sensor sizes purely by reading technical specs. The picture here will help offer you a far better sense of the sensor measurements in the Quattro and M1.

As you have seen, both the cameras provide different megapixel count and different sensor sizes. The Quattro featuring a larger sensor will make achieving shallower DOF less difficult and the Sigma Quattro will offer you greater detail having its extra 9 Megapixels. Greater resolution can also make it easier to crop images more aggressively.
