The difference between the two Cubic and Quadratic types of distortion is slightly visible. The Cubic type should be used in some camera tracking programs like SynthEyeslike SynthEyes,  BoujouBoujou,  etcetc.

Similar effects like those of the Cubic and Quadratic distortion types can be achieved with the help of a UV map. The map must be generated via a third party plugin (i.e. Nuke) or via the V-Ray Lens Analyzer tool. For a more accurate result, we recommend that you save your UV map as 32bit exr.

In the Distortion rollout of the camera parameters, set the Distortion type to Texture and link a UV map in the Map slot.
