I pretty much always pick .22 so maybe I am not a good one to ask. Any one of my guns is likely to be pointed at a critter (whether food or pest) and I like the extra edge. I don't shoot FT, but don't some guys prefer the higher retained energy of the .22 for knockdowns? I just like coming a little closer to rimfire performance with a gun that can produce these power levels. Fewer "hop offs" in the field.
That said, for yard pests of a reasonable size, the .177 would scream out of a Marauder and probably do the job on anything you're likely to encounter at yard ranges. You would have a flatter trajectory so less compensation for distances, in target. Plus, there would be cheaper pellets.
When I look at the cost of pellets, especially versus rimfire and centerfire ammo, I don't consider it much of an issue. It might add up over time if you shoot a lot but what the heck.
From what I have read, they are about equally quiet. They are really really quiet. If anything the .22 would be a little louder, and believe me, it is the quietest gun you'll find.
