Has anyone done a side, by side comparison on the same gun between these two manufacturers? I recently installed a Donny FL Ronin on my AEA Challenger Pro. While it definitely made it quieter; it would still never qualify as "backyard friendly" by anyone's standards. While I appreciate what it does do; I can't help but wonder if I might have been served with the ODB. Have any of you tried comparable models of these guys moderators, on the same rifle?
