I'd add the Griffon Armament Sportsman to the list, but, you'd want to decide what type of adapter you want and how you will use it (pack it all day attached on a hunting rifle; swap regularly and quickly between platforms?)
I have an AAC SDN 7.62 that I bought with my AAC 300 BLK SBR; I had a hunch I'd be buying a dedicated can for hunting as well but never really researched all the mounting options, POI, heat dissipation, titanium vs stainless, etc).
Right now I'm working on putting together a custom 300WM or 7MAG and trying to decide what can I want on it for hunting and accuracy.
I've always been focused on getting a Thunderbeast, and may do that for a third .30cal can, but, the Griffon and Omega have moved up on my list for price and size/weight.
Right now leaning towards the Griffin Sportsman taper mount:

Some food for thought:
Do you want a QD set up or direct thread? (or an adapter?)
Do you want the least movement in POI or at minimum a predictable change in POI?
Do you want medium or long range accuracy?
Do you plan to stay in the 308/300BLK range or larger magnum cartridges? (300WinMag?)
I'd assume your application would be semi-auto & bolt action for your first can (?)
I'd also assume you want to put a lot of rounds thru it if you are moving between semi-auto and bolt gun, but even on bolt guns some cans dissipate less heat and state a limit (for instance 2-3 rounds per minute)
Good read here on some options and good discussion re; QD's and adapters for hunting-accuracy type cans:
