This doesn't sound like you. German would get one of each without thinking twice.
You are aware of AAC's CS and warranty issues, right? And the issue with the 51T? Their new mount is the same thing but with more teeth. This removes some of the wobble and play, but it also makes the teeth finer and they were already at risk of wear being exposed like they are. You damn sure would not want one in the army, that's a fact. Saker was the solution to AAC's problems, too bad Sico made it!
If I were you, I'd get one in 5.56, 7.62 and .338 at least. The TBAC for .338 without a doubt, or Elite Iron if you want to save a little and don't mind the weight. I went that route when I was trying to stock up prior to 41F.
The only way I ever got AAC mounts that fit was to buy ten and try 'em all and pick the best fits and send the rest back. No shit, I'm not kidding. I have four of the goddamn things and I wish to god I'd just gotten Sakers. The one I do have is worth more to me and all four of those AAC cans.
AAC makes a GREAT CAN. I won't deny that. SDN6 is easily one of the best and probably the boilerplate .300BLK can. But the mount just fucking kills anything they do. It ruins it all. A direct thread AAC can, now that would probably be fine. But I really don't use those.
I have quite a few cans, and I can without a doubt say the TBAC and Saker are my favorites. But the Liberty .22 cans get used the most (Liberty is the red headed stepchild in suppressors, they mostly make hunting and range oriented stuff but their .22 stuff is just a knockout).
