For pistols, I have the Silencerco Omega 9K, Omega 45K, and Hybrid 46M so can only speak to those. Honestly, the modular Hybrid 46M could be used for all of your pistols and rifles if you just wanted one can (and only spend one tax stamp $). You can get different pistons and front caps for it to be caliber specific. I like keeping a suppressor on my 300 BLK and 460 Rowland, and use the Hybrid 46M to rotate through various other guns (along with my other rifle-specific cans, also from Silencerco), so have invested in multiple cans to minimize how many times I have to swap suppressors to different guns.
The only other manufacturer suppressor I have is the Rugged Occulus for my 22LR, so can't really speak to other pistol cans for 9mm and 40 S&W as I only own Silencerco for those. So far I haven't had any issues with my Silencerco cans. And I love the Rugged can.
