Depends on what tools you need.

Ozone is a great tool for mastering, I use it here. The presets are not necessary IMHO, I have Ozone 9 Advanced and have never once used any of the presets.

Their mastering assistant tool, which I believe is also in elements, is great for getting you in the ballpark. It has the advantage of actually analyzing your track and making decisions based on that, whereas a preset has no idea of the state of the mix it is working with.
