CAT MOB Radian model 1 30 cal 9 inch Vs Sig Rattler CGS Hyperion 188 grain discreet ballistics

Discreet ballistics is often referred to as some great ammo. I've had mixed results due to the 188 grain bullet weight not cycling reliably in lancer 300 blackout mags (to be fair Lancer's 300 blackout mags have a 200 grain weight and up recommendation).
In my opinion the ‪@radianweapons‬ model 1 with a CAT MOB .36 cal suppressor has no business competing with the ‪@sigsauerinc‬ Rattler on the CGS Hyperion, widely regarded as one of the most quiet 30 cal suppressors on the market.
