I have handled a fierce fury (non-carbon barrel) and I own a CT Edge with the carbon barrel in .300WSM. I don't have experience with the other companies.
I bought the fierce lightly used from my friend who decided to have a new, completely custom rig built up for him.
Unfortunately for my friend, he had a super terrible experience dealing with customer service (mostly the owner). It was ugly, and I truly hope that was a one-off experience. This was a few years ago, so I am hopeful this isn't the case anymore.
Lucky for me, I bought the rifle after all those issues with the company had been resolved. FYI, it was never a function or accuracy issue.
The fierce rifles are pretty sweet IMO, and I love the actions (think sako 85). Accuracy is awesome, and I have yet to hear from a fierce owner whose rifle isn't very very accurate. I'm generally in 0.3-0.4 range with handloads if I can get my act together. I think the fury line is a good value for what you end up with. I did not notice huge differences in the build quality between the fury and edge line. Triggers on the fierce rifles are really nice. I have my adjusted to 2.5lbs and it is super crisp with no creep.
If you're used to a shorter bolt throw, I believe the furys have the same 70degree as the edge. Not 54, but also not 90.
The carbon barrels can take a beating. I certainly feel better about it hitting a rock than a pencil barrel steel mountain gun hitting a rock.
Also, 4+1 in a flush-fitting detachable box mag in .300WSM is fantastic.
Essentially the only reason I didn't get another fierce is because I wanted a different barrel length than what was offered for a 6.5CM, and at that price I didn't want to rebarrel as soon as I bought it.
All that being said, I'm heavily considering the Kimber open range pro-carbon. I do like the fierce's stock ergos better, though.
