This is not scientific, but we have demos of both in our shop (SVF, LLC). The Q trash panda has been noticably quieter than the nomad at least to our guys and the customers we have demoed with. The nomad sounds good with 300BLK subs until you shoot the trash panda, and then you don't want to shoot the nomad anymore. The Griffin Paladin has been a close performer to the trash panda for us. Both (nomad and TP) have excellent accuracy and very repeatable on/off. No clear winner there. The trash panda is gonna be lighter for a QD setup no matter what you put on the nomad. At 14 oz DT, it (nomad) just gets heavier from there with QD adapters and brakes. We have used it with the keymo (very heavy), Griffin plan A and Ti brakes (my favorite setup with this can), and the Q plan B and cherry bomb (I wasn't a fan of how the plan b adapter is quite a bit wider than the nomad so we turned it down on a lathe and cerakoted it black. The gold color was very off putting against the flat black nomad.) The trash panda with cherry bomb is lighter than the nomad in direct thread config. Flash hiders for the trash panda are coming soon cause the cherry bomb is LOUD. Its aptly named. The biggest downside to the Q stuff is it's hard to get sometimes. Also I hated the Titanium anodize color it (trash panda) comes in. It's straight up metallic purple. I immediately Hi-temp cerakoted it. Most people will standardize to one mounting system, and if you aren't already heavily invested in one system (stay away from ASR) then the cherry bomb is a great mount and the mounts are some of the more affordable out there. And the can comes with 2 which is unheard of. 1/2 socket will install for you and no timing shims. Big plus. For the nomad, like I said I like the Griffin plan A. The Griffin brakes are excellent and they make a ton of different ones. The TI minimalist is my favorite to keep weight down. (The new Griffin tactical comp will not fit up in the nomad with the plan A on as it bottoms out on the blast baffle too soon. This is also true for the SiCo Omega and hybrid when using the plan A.) Hope some of that is helpful. This has just been our experiences. And just to be clear we are dealers for Q, dead air, and Griffin and I love all 3 companies. Love the trash panda and my "fix" rifle, the new wolfman from dead air is just unreal, and I love the griffin line too especially the Optimus micro, paladin, and Rev9.
