So it’s sound attenuation you are referring to? What was the difference between them as in reality - anything above 85dB is theoretically harming your hearing.Extensive testing with Bruce Potts using state of the art Sound meter, also the fact that the US suppressor manufacturers who are leading the field in silencer manufacturing almost exclusively build only front mounted suppressors.
I guess the sound is one aspect of it but muzzle flash, balance, length addition, weight addition, maintenance, longevity are all factors in moderator selection.
