There really isn't any.

You can use the camera to find how far away the target is. It's even easier to do with the camera even better results with the light ring.

You can use the little mount FIRST gives in the KOP for tilt on the camera.

And you can use the accelerometer in the KOP if you care to have one.

Hence we are going to use the axis camera.

All you get is bragging rights.
