You have to take into consideration some barrels come with matching bolt. J&T/Double Star will sell barrel alone or with the bolt which of course adds to the price. Brownell's barrel comes with matching bolt. The BHW barrels do not generally include the bolt so you need add $50-$80 for a bolt which you have to purchase from a seperate vendor.
I know a couple people who bought Stainless Steel 6.5 Grendel barrels from J&T and they are satisfied. Only downside to the J&T barrels is they are 1:9 twist whereas some people like 1:8 twist as they plan on shooting 139-140 grain bullets. The 1:9 twist probably isn't optimum for the heavy bullets. My 1-9 twist barrels are accurate with bullets from 85-123 grains. I personally have not tried to shoot any of the heavier 6.5/.264 bullets.
If I were choosing between Brownells and BHW I'd probably buy a BHW barrel with SAAMI 6.5 Grendel chamber and 1:8 twist even if it cost more.
