I own more damn cans than I can think of right now... I can tell you the Saker is my go-to "military" can. By that I mean it has a QD mount and can be fired FA if desired and will usually be made like a tank. Generally made from high end steel alloys. I have a bunch of cans and several AAC QD cans along with the Saker. AAC makes a good military can but a shitty mount they refuse to move away from.
It'd take me too long to compare them here. Just take it from me that you won't be disappointed in the system at all and it's also modular as a motherfucker --uses almost everybody's mounts (with adapters), even shitty ones, and has several different end caps you can replace. The 5.56 endcap renders the 7.62 can quieter than the 5.56 model which I have, although the 7.62 model is a bit bigger and heavier than the 5.56 dedicated. They have breaching endcaps, etc. The 3 prong mount is silent, no tuning fork shit. Stellite vs. Inconel (either is overbuilt in that respect). Saker mount is amazing, the can can be attached with one hand and fully using gross motor control, just twist and it'll lock up in less than a rotation, no fingers needed, so it goes on and off easy as shit. Stellar CS, love Sico.
Sico is a company to watch, they've REALLY stepped up to the plate over the last few years. I have their Omega 9k too, ever need a short .300BLK or 9mm can, this one is hard to beat.
You can spend more on a SF can or a KAC can or whatever, but Saker will likely be the better buy at the end of the day. I'll be buying more for other rifles and had they made a brake for my KAC rifle I likely would have used the Saker on it but went with the KAC can due to the 3/4" threads and existing mount.
