Depends what you are doing with your compressor. Higher pressure will give you a little more use time but as said takes longer to get up to speed on initial start up. Compressors are built by stages for higher pressures, single acting or double acting for faster initial start up, working pressure for various kinds of work, and flow for volume demand. Spray painting requires low pressure high volume. A jack hammer requires high pressure and high volume. Testing safety valves requires high pressure low volume. Testing ballast valves on a submarine requires extremely high pressure and low volume.
