Quietest off the shelf PCP .22 repeater?

Everyone's ability to tinker/tune is different and that's why I have my FX guns, they are the easiest gun to tune without taking apart the gun. Most guns need to be taken apart to some degree to tune, if you are mechanically inclined then most guns are pretty easy to tune especially with a regulator.
As far as energy goes I know from experience that 7FPE at the target is plenty even with vital shots on squirrels with the right pellet. So at 35 yards anything over 9FPE at the muzzle is plenty but headshots are still preferred but you get pass through most of the time with headshots. I use 177 hades at 8 FPE or 600FPS at the muzzle and drops squirrel quite easily, no passthrough vital shots. With .22 caliber the problem is the speed is so low at 9FPE you need to know your drop well, 650-700FPS is a good speed with not a lot of drop out to 35 yards if you zero at 20 yards. One of my guns at 680FPE has the near zero at 20 yards and far zero at 35 yards, slightly hold under at 25 but so little it doesn't make any difference on a squirrel. Just need to test out the speed and pellet combo, I'm a fan of the hades. If you have large properties then who cares but if you are in suburbia then low the power the better especially in case of a miss or ricochet. Accidents do happen!
For reference my idea of quiet enough but can be better setups: Donny Sumo caliber .22 moderator to quiet down 7 FPE gun with a quiet tune, 7 inch moderator on my other .177 gun at 8 FPE, emperor for my 8 FPE pistol/carbine........I'm a bit over the top on trying to be quiet, anything over 75db at arm's length is loud.
According to this video the HW110 even at about 25FPE it's only 70db(10feet away) which is amazing, in UK videos the .177 HW110 is barely a click at 11.5FPE. A taipan with PEEK valve and a good moderator would likely be very comparable but might not be as quiet without some additional work by the likes of Motorhead, but it's a much higher powered gun.

@11.5 FPE, just listen to that stapler!

You don't "need" anything more than 12 fpe honestly. But in .22 I would want 22-28 fpe to keep a 15.9 or 18.13 grain JSB shooting nice and flat.

I'm new to airguns, so please forgive my ignorance, but how much flatter would a .177 be over a .22 at ranges out to 35 yards, assuming both are tuned for decent quietness and at an energy fit for squirrels?

So, as far as trajectory goes, a mid power .177 and mid power .22 will shoot at about the same drop out to 50 yards. But the .22 will be carrying just under double the energy. But the .177 will be more than twice as quiet. I have an 18 fpe .177 that shoots a mid-weight .177 @ 880 fps and I'm looking at 1.3" of drop at 50 yards. .22 shooting a mid-weight 18.13 @ 880 would be about 1".
The catch is that .177 is literally only hammer ping when it is fired. And I have yet to shoot a mid-power .22 that even comes close. I've always lived in suburbia and needed to be super stealthy with my pesting/plinking.
I'm a huge .177 advocate and people who care about .177 are waning by the day it seems. Honestly, with today's guns, there's not much reason to not just go .22, unless you're plinking/pesting short range (<50 yards) and/or need the decreased noise.

I have some free time this morning and entered some numbers in the desktop version of Chairgun.
I used a 1/2" kill zone and a 2" scope height for both 177 and 22.
I picked Polymag shorts for pellets as I believe they are considered good for crows and people certainly use them for squirrel. I picked the shorts as the regulars don't always fit in magazines.
I used 15 FPE but have no idea if it's sufficient for crow.
Please note that scope height will likely be different between a traditional rifle like the HW110 and a bullpup like the Taipan.
With a kill zone of 1/2" the 177 will be 1/4" low at 17 yards, 1/4" high at just over 25 yards and a 1/4" low again at 38.7 yards.
In other words, the point blank range (PBR) will be 15 yards to 38.7 yards for the 177 with the details I selected.
The PBR of the 22 Polymag short will be 11.8 to 31.5 yards. At 35 yards you would be 0.45" below your kill zone.
In my case I prefer to have my pesting rifles set up so that my closest shots are within the PBR. The reason being is that it's these shots that I often have to take the quickest so I just want to aim and shoot.
In your example if I knew I'd have shots between 12 and 15 yards I'd prefer the 22 slightly over the 177 and I would just holdover for shots at 35 yards.
But if quiet was the premium and 177 was quieter I would choose the 177. The 3.2 yard near zero distance difference would be no big deal.
Back to scope height. Sticking with one caliber, I'll choose 22, if I lower the scope height to 1' the PBR changes to 6.2 to 26.5 yards. If I raise it to 3" the PBR changes from 16 to 35.3 yards.

If you are comparing a .177 or a .22 at the same energy output, like @Scouty did, then I'd go .177 hands down, as the .22 will have much more drop at even moderate ranges (35-50 yards).

My bare unregulated Marauder is noticeably quieter than my Air Arm Ultimate Sporter with its factory moderator. Not a big deal though to add a Sumo moderator for less than $200 as I have done with my Benjamin SAS and make it even quieter.

FX Royal .22 cal. 880 fps 18gr. JSB with a factory installed Hugget. Hands down is the quietest pcp ever made.

By the way I love the power setting dial on the S510 Ultimate Sporter. When I am shooting at closer distances I can twist the dial and reduce the power by half and reduce the noise as well. The S510 is also getting quieter as I put more rounds through the barrel.

If you will be buying a US spec, or FAC power level rifle, they will have very similar trajectories, but the .22 will have almost twice the fpe. If you shop for a 12 fpe rifle, which is common in Europe, then the .177 will have a significantly flatter trajectory. If you are firm on wanting one without a moderator, then a 12 fpe rifle in .177 may be your best option, and the power is adequate for hour 35 yard squirrel scenario.
