There are many different tools that can be used for measurement, but the degree of accuracy is dependent upon the tool. For example, a ruler can measure distance with a good degree of accuracy, but for a more precise measurement a caliper should be used. The difference between a brass pressure sensor and a stainless steel pressure sensor is similar if we think about it in these terms:
AEM offers high quality stainless steel PSIg sensors in 100, 150, 500, 1,000, and 2,000. Gauge style pressure sensors reference pressure above atmospheric pressure. When exposed to atmospheric pressure, gauge style pressure sensors will read 0 psig. Gauge style pressure sensors are commonly used for oil pressure, fuel pressure, brake pressure, nitrous pressure etc.

Example: Brass Pressure Sensor used for a Boost Gauge - Reference/Information for knowing manifold pressure, not for ECU calibration.
Use a Brass Pressure Gauge Sensor where you need a good reference to what pressure is being seen.
Example: MAP Sensor information for the ECU - Calibration/crucial information for the ECU.
-Stainless steel body, with high quality sealing which makes it impervious to fluids.
Use a SS Pressure Sensor where you need exact details of the pressure.
