I have 13 or 14 suppressors at this point. I am a "one suppressor per firearm" kind of guy. I have everything from general purpose do all cans to ridiculous unitasker cans. I regularly shoot with other people who also enjoy collecting random suppressors and playing with them, so I've tried out a good variety of them.
What I would recommend to the OP would differ greatly depending on what the OP wants to do with the can.
OP isn't sure: Rugged Radiant, Dead Air Nomad, or YHM Resonator. Great general purpose suppressors that will always have a use.
OP wants a hard use general purpose can: Dead Air Sandman S, Rugged Razor (or Surge), CGS Helios QD, TBAC Dominus (based solely on TBAC reputation and early metering, haven't touched one yet), Griffin 30SD-K, or Silencerco Chimera.
OP wants a lightweight short can for 5.56 only use: YHM Turbo K. Seriously, everyone should own at least one of these. The Resonator K might seem tempting but it meters about 10db higher at the muzzle than the Turbo K. Meters about the same as the Turbo K at the ear, but having an order of magnitude more noise coming out of the front of the gun is enough to make me recommend the caliber specific can. Seriously, this is the can to own for a home defense rifle in 5.56. Performs great, low backpressure, cheap enough that if you use it for its intended purpose you aren't going to cry if you have to long term loan it to the police.
I have used the newest gen OSS suppressors. They are a cool concept and I think the idea has merit, but they are pretty loud. As in still probably ring your ears if used indoors loud. They are good for full auto fire as you'll likely have a lot of earpro on anyway, and they do reduce concussion enough that shooting belt feds at the range all day doesn't make your head feel full of playdough afterward. I think another generation or two of refinement needs to happen before I seriously consider buying one. I think the CGS Helios QD is a better option for similar performance at the moment.
Ultimately anything from a reputable brand is going to be pretty good. I don't prefer the Silencerco muzzle devices and ASR attachment system, but it is fine if that's what you have.
