Hi all,i disagree with you.It's an apple and orange matter.
Concrete Limiter is a tracks\mixing limiter concept.Infact is a plug with limited controls and fixed algorithm.
Ozone and Tracks stuff are dedicated mastering limiter.I would recommend you that don't use a limiter in a Mixing prj on muster bus couse you must preserve all your headroom and dynamic for mastering session.Again,the limiter on muster bus can change all song's eq making wrong decisions on tracks eq.
I always export my 32 bit wave project in an other mastering session and i use a few mastering plugs to focus my final sound object.I use Voxengo Elephant on mastering session,It has many controls to preserve original dynamic.
