With Bartleins reputation for accuracy and dependability, I'm going with a Bartlein. I know Proof has had alot of time building and proving themselves and have excellent CFW barrels. I'm just gonna stick with the barrel I've had the most accuracy out of. That's Bartlein. Even tho I'm a hunter and not a competitor, I've never heard the Proof Research name on the list of winning competition barrels. It was a real toss up tho. Almost went the other way. It was just my past experience with Bartlein that made the decision for me. That said, I'll try a Proof on my next CFW build for if no other reason, to compare the two. I do know Proof makes a little lighter barrel than Bartlein when compared identical contour/length barrels.
