Pros:

1. Reliability. If you have a 6-wheel WCD, you drive the center wheels directly off the output shafts of your transmissions. Even if every chain to the outer wheels fail, you should still be able to drive your center wheels.
2. Maintainability. Because the wheels in a WCD are cantilevered, removing a wheel is as easy as removing a snap ring. No need to take apart your frame to get at a wheel.
3. Simplicity. No outlandish parts or software required to use.
4. Drivability. Driving a good 6-wheel WCD is incredibly smooth, thanks to the dropped center wheel.
