I really like my Griffin 30 sd K ... but it's the only can I've ever shot. It's comfortable to shoot hogs with no ear pro. I've noticed no degradation in accuracy with or without the can on. thinner barrels have a bigger POI shift, as the weight causes them to bend a bit. virtually no POI shift on my heavy profile 16" barrel. Just check your zero and adjust your scope with the can on, it's really simple.
I like the gate lock qd and now I have a Griffin muzzle device on almost all my rifles.. and it discourages me from buying more cans, I'm not sure if that's a + or a - but it saves me money.

https://pewscience.com/ they haven't tested many cans yet but the CGS Hyperion appears to be the current winner on sound mitigation.
The AB suppressors someone mentioned above look very interesting. With a gas gun, a low back pressure can like AB or OSS should mean cleaner running and less gas in your face, but an adjustable gas block kinda takes care of that too.
