Why radians are preferred over degrees as a unit of measure of an angular displacement?

Radians relate a distance walking outward from the center of a circle to a distance walking around the outside of a circle.  Measuring an angle as ‘distance around the perimeter per distance away from the center’ makes the notion of angle something universal, something that doesn’t depend on what choice of units you have made for measuring length or how many pieces you have decided make up the ‘standard’ number of circle divisions.  In contrast, 360 degrees is arbitrary, largely chosen because it has a lot of integer factors that make it easy to figure out how to fairly cut up a pie with pen and paper.
