I use Ozone 10. It's straightforward, easy to use, and it delivers a very nice polished final mix.

Most of the time, I simply add it to the master buss on my DAW and let it do it's thing. It analyzes the musical content, tells me what genre it is with a very high accuracy rate, and sets up a mastering chain for that genre. Often, I really don't have to do anything else. However, I will often turn off the maximizer module in the chain since it tends to really drive the wave form into a brick.

Aside from that maximizer issue, I recommend Ozone 10 as one of the easiest ways to get a nice polish on the final mix.
