George,

The distance of each sensor is a feature and has nothing to do with precision (sensible).
Accuracy is measured when you take the sensor and make several measurements. The lower the average measured distance means the more precise the sensor is. The LJ12A3-8-Z/BX is more accurate which is very important for our purpose.
Of course if you use glass then you will need a sensor with 8mm distance but the OP asked for the best sensor.
