The stiffness and cooling advantages with CF are a myth.As far as caron barrel goes, I could care less on looks. Carbon looks cool, fluted steel looks cool. It's a wash in my mind. Why I picked it is just because it seems you'd be getting a stiffer (less whip) barrel over a smaller dia steel. Probably negligible and the care taken when manufacturing and rifling the barrel is way more important but it makes sense to me that a larger diameter barrel would be an advantage. Plus the cooling advantage. In all honesty though I bet I could get a fluted #3 and be completely happy.

Tests have shown that a #3 ss barrel is stiffer than a Sendero contour CF, and CF acts as an insulator to the super thin steel core which leads to other problems.
I've had 4 deep fluted barrels now, two Spiral fluted by Kampfeld. They've all shot .3 or better, whatever your issue was it likely had nothing to do with the fluting.I’m leery of aggressive fluting. Had a 6.5 saum bartlein that kampfeld spiral fluted and beanland chambered that I wasn’t happy with and 2x seekins havaks that didn’t shoot well either. Beanland and Travis @ TS have both told me they aren’t a fan of aggressive fluting (especially on sporter contours).
A few years ago I decided to give preferred barrels a try and had terrible luck with two that were fluted.
They both copper fouled real bad and I'm sure the accuracy issues were a matter of them being cheap
