Certainly, the Lilja, Kreiger etc clan on the BR circuit gets more play, and they are certainly super fine barrels backed by superfine companies and craftsmen. However, the fine shooters that can take advantage of the
perceived difference of 1 or 2 hundredths of an inch are very rare, maybe less than 500 in the US. The best shooters use certain barrels because they want to cover every base. They are a clan, a fraternity, and they, like many of us, might equate more expensive with better.
Frankly, I could have a panda actioned, Kreiger Barreled, Speedy Stocked rig with my best loads and likely get smoked by a top notch BR competitor using a Savage varmint rifle in .223
It's more the shooter than the rig. But for a few shooters in the rarified air of supershoots, most of the rest of us would be well served by a standard douglas barrel, none of which I have ever seen shoot poorly.
