Typically, it can be hard to picture the gap in sensor measurements only by viewing a spec sheet. The graphic underneath may give you a greater sense of the sensor sizes in the Quattro and TX55.

As you can see, the 2 cameras offer different megapixels and different sensor measurements. The Quattro using its bigger sensor is going to make achieving shallower DOF simpler and the Sigma Quattro will render greater detail with its extra 13MP. Higher resolution will also allow you to crop photographs a little more aggressively. The younger Quattro should have an advantage when it comes to sensor innovation.
