AFAIK there is no "best way", but I suggest you buy a quality air pressure gauge and only use that gauge to check the pressure.
IMO All tire pressures should be within 2-4 pounds of each other if there are no obvious defects, such as a leaking valve stem or flat tire and always check all the tires at the same time, preferably when they are "cold".
Over a period of time, you should learn if your gauge is reading the correct pressure or not.
