I'm not worried about split times. However, sharp recoil causes a little bit of pain with each shot and it accumulates. My first shorty AR was a 10.5 inch pistol with a huge gas port. It was so overgassed, it slapped my shoulder and stung my trigger finger. Being stubborn as a mule, I tried to power my way through it. The pain only got worse with each shot and I ended up with broken capillaries from the butt-pad. No, I'm not a tough guy and I usually only wear a tee shirt when shooting and I did go through a couple of hundred rounds each session. But it hurt even through my heavy jacket. To hell with that noise! Shooting is supposed to be fun. That started me down the road of experimenting with different gas flow (adjustable gas block), action springs, buffers, ammo and extractor springs.
You know what a factory 6920 lacks? That sharp recoil. A Colt civilian M4A1 is even softer. My factory SBR 11.5 inch Colt with an Omega suppressor is a soft shooter. To get there, I used a BRT gas port reducer in the FSB sized for shooting 100%. With a bit more tuning, I settled on a Sprinco rifle length action spring and an A5H2 (whichever one is about rifle buffer weight). The result is a soft shooting suppressed SBR.
Bottom line- Life is too short and I'm too old to shoot a sharp recoiling AR, suppressed or not.
Note that I use the terms "sharp" and "soft" recoil, not "increased" or "decreased" recoil in this discussion.

The OP is buying a factory Colt 6960. It’s a factory midlength.
Not a defective with a gas port like a porn star’s orifices.
Shoot the gun. Fix if needed. If not, needed don’t mess with it.
The idea that any gun that is functional un-suppressed must be modified sight unseen because it is presumed to be overgassed when suppressed is not a valid assumption.
The gun, ammo and suppressor are a system so all are factors. Change a factor you change the equation.
With proper choices it is possible to get a gun that is properly gassed both suppressed and unsuppressed.
Hodge is the prime example but I’ve been able to get similar results from Primary Arms house brand (Expo) barrels which are 1/4 the cost.
PSA was mentioned up thread but there are “premium” guns like Noveske which are severely over-gassed.
Going back to cans:
As stated up thread I have an Omega, I was an early adopter. TLDR that can, like the AAC M-4 2000 has significant back pressure. I’ve seen it cause malfunctions in multiple guns that ran fine with SF, YHM, and Dead Air cans.
I’d rather relegate it to bolt gun use than re-engineer my guns around a poorly designed can. Particularly when a YHM can at half the price doesn’t require the Rube-Goldberg effort.
Yeah I've decided my Omega will stay on my 300 BLK bolt gun and am pretty much committed to a dedicated 5.56 suppressor -- very likely a YHM reduced blowback model.
Amazon dropped off a set of Daniel Defense fixed BUIS and a QD MLOK sling attachment today. The Colt will be in my FFL dealer's hands by Monday.
in my experience every solution to running an AR suppressed has limits. I agree with HCM you should just shoot what you got and adjust as needed. The BRT gas tube is a great way to adjust pressure but I have also been satisfied with adjustable gas blocks and carriers. The carrier is an easy drop in solution -0 my two bootlegs work just fine.
edit: The YHM Turbo K is a great value 5.56 suppressor. I have two and will probably buy another at some point down the line.

Ok…….
I’m not here to convince anyone. If you feel that strongly about something without ever having used one, then any words of mine are not going to make anyone want to. Maybe I’d I got kick backs but alas, my opinion is only my opinion and worth exactly what you paid for it.
You can get much more of what you want with a kind word and a gun, than with a kind word alone.
? I literally said I used piston guns repeatedly in my post and all they do is move the problem from one set of parts to another, in my experience, and gave 3 examples. Two of which are guns you can actually still buy new..and one might come back into play if Colt sacks up for it. And if they give it an adjustable gas piston...I might even be willing to give it a shot again.
