One do all can is the starting point desire of every suppressor newbie, most wind up with at least a few after they figure out that a few slightly more specialized cans are a much better solution than one super-compromise can.
The usual path folks go is a rimfire can, a .30 cal rifle can, and a .45 cal pistol can.
Rimfire cans accumulate a lot of lead fouling and should be user serviceable, and preferably made of materials that allow for easy cleaning with harsh solvents like stainless steel and Ti. The top rated rimfire cans to check out right now would probably be:
Dead Air Mask HD
Rugged Occulus 22
TBAC 22 takedown
SiCo Switchback 22
Energetic Armament NYX
As for rifle cans, lighter is generally better, short is nice, but you strike a balance between length and suppression performance. Extreme toughness is a catchy selling point, but most folks aren't running their suppressors on short barreled machineguns, most mainstream cans out there are tough enough for most people's realistic uses. Over the top toughness in cans is fine except it almost always comes at the expense of weight, or cost, or both. Mounting options are an important consideration with rifle cans, it's nice to be able to switch between direct thread patterns, and QD options on the same can to fit different uses, conversely, being stuck with a single mount and no other options can suck. The Omega mount thread pattern (1 3/8" x 24) has become somewhat of an industry standard, cans with this mount thread can be used with a multitude of QD and DT mounts. I do not see near the buildup in rifle cans as I do rimfire and pistol, unless you specifically intend to shoot lead or coated rifle bullets, I would not want a user serviceable can as they are always heavier. In my latest rifle can purchase, I placed a lot of emphasis on weight, mount compatibility and length, my top choices were:
Dead Air Nomad 30 (what I bought)
Energetic Armament Vox S
SiCo Omega 300
Other cans I'd also look at now would be the Rex Silentium MG7, Rugged Radiant, TBAC Ultra 7, and Griffin Explorr.
For pistol cans, I think user serviceability is important because I like to use cheap lead and coated pistol bullets. Like with rimfire cans, I like SS (more common) or TI baffles.
For .45 cans, the top rated mainstream options seem to be the:
Obsidian 45 (got mine a few months ago)
Dead Air Ghost M
AAC Tirant 45 M
All three are modular cans, so you can run them in a short and long configuration. I like the Obsidian in short configuration on my 9mm pistol, and long configuration on my .44 mag rifle. The Obsidian is big on a .22, but actually sounds alright.
I'm not sure about the other two, but the Obsidian .45 is rated for chamberings like .45-70, .44 mag, 450 BM and 350 Legend out of 16" barrels, if that matters to you.
