I've used the massenburg option for the Oxford as a demo and own the Massive Pack versions of both plugs. The only difference I could determine between the standard Oxford and the Massenburg option was the maximum width of the Q and the amount of overlap between frequency bands. If I set both versions to roughly equal settings, they sounded identical to my ears.

The newer MDW version however is a completely different animal -- easier to use and much better sounding IMO. MUCH sweeter in the mid and high frequencies and tighter in the lows. The only advantage the Sony has is its ability to load 3 band and Filters only versions to save on DSP.

If you are only going to buy one I would definitely recommend the MDW.
