Not familiar with the Fierce, but both the Cooper and Christensens are about another grand over the Nosler I believe.
The Christensen Ridgeline can be had for under $2000 and that's Christensen's "entry-level" rifle with a carbon wrapped barrel. It's only "entry level" because that's the least expensive gun Christensen sells with the carbon wrapped barrel - it has loads of upgrades no other "entry-level" rifle has of which I'm aware. The Mesa (steel barrel) can be had for significantly less - about $1200. I own two Christensens, but both of mine sport steel barrels. One that I think was called the "Classic Steel" and a Mesa. Both are excellent rifles and if/when I add a 280 AI to my collection it's very likely to be a Christensen Ridgeline.
The Coopers are more expensive indeed. $2200 "street price" for a Model 52 I think and other models are more expensive. I don't have any experience with them.
