Which Pressure Gauge Is More Accurate?

Which pressure gauge is more accurate?

This is because some gauges are more accurate over the middle half of their range than over the first or last quartile. For example, a 100 psi gauge with Grade A accuracy is accurate to 2% of span from 0 to 25 psi and 76 to 100 psi while being accurate to 1% of span from 26 to 75 psi.
