This dances around the real point. You could just as easily have asked where do Ozone and Finalizer stand in comparison to any other combination of dynamics processor, reverb and equalizer.
The point is there is *nothing* that makes either of those products "mastering tools" any more than any other signal processor is a mstering tool. Furthermore, there is nothing of any special quality to those two products that makes them especially suited for actual "mastering" over any other signal processor.
These companies simply decided to create a new market segment - and unfortunately completly distort the definition of "mastering" in the public's eye in the process - by talking basic audio tools of types already available, throwing them together into a single package, and calling them mastering tools. They're the home recording version of what Sony and Panasonic and the rest did when they decided to take cut-rate versions of component tuners, preamps, amplifiers, turntables and tape decks, throw them into one box, and call them "compact hi-fis", even though there was nothing "high fidelity" about them.
