What MultiBand Compressor Do You Prefer?

Many MBC plugins on the market and everyone has favorites.  Which one do you like best and prefer for mastering?

I'm no fan of these things, but I would say that Ozone is close to the top of the pile if you really need one.

I'll repeat myself from your other thread, but others may be watching ...
I like the Sonitus for surgical corrections - the UI is great for that kind of work, and it's very effective.  On the rare occasion that I use MBC for mastering, it's usually Ozone.

MBC is one of the most abused tools I've ever seen.  However, on those rare occasions where you need it, it's great.  I recently used Ozone'S MBC on a mastering project.  I almost always prefer single-band compression, but the mix I recieved needed slight repair.  It was, overall, a really good mix.  But some master bus compression had been added and, at times, the kick was causing the mix to duck.  During musical parts it was fine, but when there was singing, the vocal ducking was audible.  I used Ozone's MBC to minimize this effect and it worked really, really well.

So why Ozone?  I have several MBC plug-ins on my machine.  First of all, Ozone has a full multband dynamics suite, not just compression.  It is, by far, the most feature-rich dynamics processor I've seen, as everything can be adjusted for each individual dynamics module, as well as each band.  That means that you can set 12 different attack times simultaneously.  It's those options that I love.  Also, it doesn't have a 'sound'...Completely neutral.  It does exactly what I tell it to do.

I've limited use of MBC.

Recently, used AA limiting plugins - adjusting the band limiting frequency range to (120 - 360) / as well as playing with attack and release times.

Interesting result: fundemental frequencies are tightened (drums / bass) while higher sounds (guitars /vocals) are floating free in space.
