Kev, I'm a big Ozone fan and I also own some waves stuff and the waves are no slouch. You probably aren't hearing the huge difference someone would hear who went to Ozone from nothing or from using lessor plugs. I didn't hear a huge difference in Ozone and Final Mix when I first switched except that Ozone to me was "silkier" for lack of a better term. You should hear a very discernable difference among the presets within Ozone itself especially among different genre presets. Within genres the changes in sound from one preset to another can be more subtle.
