Hey @Steven - these are good questions. Both sensors have their own advantages and disadvantages.

The PiicoDev Laser Distance Sensor is high-accuracy, high-repeatability and has a higher cost.

The PiicoDev Ultrasonic Rangefinder has lower accuracy, repeatability and cost - but is more suitable for measuring eg. the height of a liquid (where the IR laser might just pass through or scatter).
