Suppressor questions

I have a rifle in 6.5 cm I want to suppress it. Im looking to get a suppressor that is hub mount supported so I can pick my qd and not be stuck with it. Im looking and suppressors and they all look super similar so I was wondering from all of your perspectives that have more experience then I do, what brand of suppressor do you recommend? What sets them apart from the competition? Also if you have two cents on keymo vs rearden atlas I would love to hear that as well. Thanks in advance!!
