Regarding Ozone supposedly sucking the life out of your mix....
First, that is not limited to Ozone. Anyone can do that with the default plugins that come with any DAW including BB & RB.
Second point and probably the most important one. If you learn what you're doing and use only what you need, you can use any preset in Ozone and still have a dynamic mix. Some tweeking of any preset is always a good idea. AND.... there is a PDF that helps newbies learn about using compressors and limiters and all the other tools in Ozone....and the best thing is, it applies across any plug in used in the mastering process.
It is ultimately YOUR choice and by the decisions you make whether your mix looks like this which is compressed to the max:
or if it looks like this one which is also quite loud but still retains the dynamics it needs to impart a pleasant listening experience:
A good wave editor lets you see the final wave. This is one time I do recommend using visual information in the mixing process. And yes, a simple compressor adjustment can make the difference between the top photo and the bottom one. And unless you have good ears, it may be difficult for a newbie mixer to hear that difference but your eyes will spot it.
My 2 cents
