I have had this gauge for decades. There are other gauges 5 times the price but I don't need one for science or pro racing purposes. The cheap pencil ones can vary 5-6 pounds and are worthless. The tire store gives them away and I tested 4 of them and each one was different from my accu-gage (some by quite a lot).
Everything I read says that the smaller the pressure spread 0-60 versus 0-120 psi will give you a more accurate reading. As far as accuracy is concerned, each gauge may vary by a pound or two but if you use the same gauge you will know whether the pressure is going up or down (hey, temperature of the air and cold tires versus just driven will cause a variance of a few pounds).
