If you shoot a moving object, and sometimes even a stationary one, it makes more sense to crop afterwards. It is very difficult to get perfect framing in crop mode. The only advantage I see is file size.
The only advantage I see to owning a very fast DX camera is shooting little birds in flight. I would prefer an FX D4 for that
