Other than the Distressor ratio names, the key difference with other compressors is the ability of dialing 2nd and 3rd order harmonics to the signal within the same plug in as you'd do with a saturator. Distressor deviates from the typical settings you'd find in any other compressor. Although some parameters are essentially the same, the distortion component is what makes its sound unique, since you can layer it with the compression and use it on any kind of source material.
