I've got five Criterion barrels and every one of them is a fantastic shooter. Truth be told they shoot just as well as my Bartleins and Kriegers. They all reside on prairie dog rifles which demand a high degree of accuracy and they deliver it. I don't have any Wilsons so can't comment on them, but for my money I'd go Criterion. Between the three I've put on for a buddy and the five I have we haven't had one that didn't shoot great yet. I'm a big believer in them, they're the best value barrel out there in my opinion.
