The answer depends on your pressure cleaning application. When you have heavy soils to wash, GPM (gallons per minute) can be most important. When you have stuck-on grime, PSI (pounds per square inch of pressure) can be most important.
Despite what you see in advertisements or on a product label, volume is the deciding factor and a quality pressure cleaning system will provide the proper balance of volume and pressure.
