Rest assured if you can't get pro sounding results out of Ozone you'll not be able to get pro sound out of anything else you choose to use.
That's the whole case for Ozone in a nutshell. Nothing else is easier to get good results with, at least as far as limiters go. There are better multiband compressors, better equalizers, better tape sims / harmonic exciters, and certainly better reverbs. But the limiter alone is worth the price of admission.
