How long is your barrel? Abd what caliber is your rifle? Obviously, “the right amount of suppression” is the most important consideration, but after that, overall length is a primary consideration when picking the right suppressor.
Overall length also plays into how quiet the suppressor sounds. If I have a 16” or 18” barrel, I don’t want a 4” suppressor unless it manages to be ridiculously quiet. A suppressor that sounds fine on a 22” barrel can sound fierce on a 16” barrel.
I work with a general rule that I want my overall barrel+suppressor length to be no more than 26”. I want my overall rifle weight no more than 10# (rifle, optic, sling, suppressor, and any other permanent accessories). Ideally, I want the balance point right in front of the magazine well. I find that works best, for me, when I take an offhand shot.
This is my spreadsheet from when I was shopping around for a suppressor a couple of months ago. This resulted in me getting the AB Raptor 8 and 10. The Reaper, Airlock, and OG 6.5 were not out yet at that time, so I added them.

I currently own the Scythe (don't get one of those), the two AB suppressors, an OG, and a Griffin Recce for my AR.
I have an OG 6.5 in jail. The OG 6.5 is going to go on a 24" .25-06.
If you want a 6" suppressor, I don't see how you could go wrong with the Reaper. It will have a reflex option available sometime this winter as well (for an additional $300-400 and some more weight.). Of course, the Nomad Ti XC is not a bad option either.
I have started to look more into SE db ratings, not just SE dbA ratings (SE DB measures the sound that potentially affects your hearing, SE dbA weights the sound you can hear). If you want a longer version of my current spreadsheet, it is here:

If you want a shorter, lighter suppressor primarily for hunting, the Airlock seems like a great option. It reportedly heats up really fast due to how effectively it traps gas, so probably not ideal for a range session. I'm planning to eventually get one of those, but I really like the reflex cans and I want to wait a bit to see how well other people like the Airlock after this hunting season before getting one.
