Overall I think its the compensator is the best. On defence suppressor is good on some guns, but compensator is really good on all the guns. It decreases recoil by quite a bit.
Muzzle on most of them because the first three shots matter the most and those are the ones that don't have any recoil so that's why it's on the majority of my guns
It really depends on the weapon man Muzzle: reduces vertical recoil Compensator: reduces horizontal recoil Flash hider: reduces both vertical and horizontal If you want to know what’s the best for certain guns dm me
