At the risk of saying something controversial... Ozone doesn't really offer much. It is really just EQ, MB compression and a limiter, none of which are that good. Also the package seems to be designed and marketed for people to just throw up a few presets and vacuum pack their tracks, which Ozone isn't very good at. The 'mastering reverb' is just...'reverb' and the spatializier stuff is superficial coloured distortion.
Yea, if you're dishing out a grand to stick some presets on your tracks, you're wasting your time. You gotta learn how to use it to its full extent before it truly starts to shine.
