I use a compressor and/or console emulator of some sorts to give a small amount of glue and color, depending on the mix.  Might be a vintage Fairchild-style to a clean comp... just AB some until it makes the mix pop. I'll prob have an eq mostly for hi-pass and lo-pass if needed.  I like the metering plug from T-Racks cause I can watch the spectrum, phase, peak and RMS to keep it reasonable as a final mix before it goes to master.  

I have to agree with all the folks that say Ozone 5 (or 4). It is a bit on the expensive side, but holy cow, the difference it makes in the final mix is astounding. When I A/B Ozone, when it's in bypass (the original mix), it actually sounds sucky by comparison. There are some efx plugins where you A/B the results and can barely hear any difference, but with Ozone, just using some of the default templates, it's like night and day. In general, I love iZotope products, I have Nectar for vocals and Alloy 2 for mixing. They are definitely my go-to mixing and mastering plugins!
