Well, they all are good comps with different features. THe rnc offers something either behringer offers-r n c mode where 3 comps are linked interactively to reduce compression artifacts. The autocom has an enhancer that adds airiness as the signal is compressed to reduce the dulling effect. It is also cool that is has a side chain filter that keeps energetic bass frequencies from triggering compression. THe composer has a limiter after the compressor. They are all really clean units and the behringers are copies of drawmer units. Oh the rnc won't do dual mono. It'll do mono, stereo just not dual mono.
