   I have about 20 different tire gauges, probably 3 of those will read   
   matching pressures, most are within 1-2 psi. I;m not real worried if the   
   tires are 33psi, or 35 psi, as long as they all read the same on the   
   same gauge. I love the Journey as it shows PSI on the TPMS display.   
   With the car setting in the shop and cold tires, I can check them and   
   find each one is at 36 psi. Then look at the display and see it showing   
   every tire at a different pressure, both higher and lower but usually   
   within 2 psi of the gauge.   
      
   As for which is better, it's a crap shoot unless you have it tested and   
   calibrated regularly.
