It all depends on how ya look at it.
Wear & Tear: Green Mountain is as tough as they come & will outlast any of the barrels when figuring rounds per barrel.
Looks: Rice Barrels are the smoothest in & out. IMHO, outside polished finish is a waste of good machine time & $ to me as I draw file my barrels & take that purdy finish off. I would prefer he knock off the fine polishing of the outside & cut the barrel price $20 each.
Value: Colerain. Best barrel for the money & have never had a bad one from dozens I have used. Also have always had good accuracy from them. They cover most swamped barrel applications & wonderful availability on them.
Accuracy: Goodoien. Jim's barrels will outshine all of them off the bench. If I was building a match rifle, his barrel is the first choice.
Quality & Looks: The Getz if a great barrel, just a delay in getting the ones ya want sometimes. Very nice work inside & out & a quality barrel. I use them if I can get them & if the customer wants to go the lil extra from the cost of a Colerain.
But I guess my answer to the question is Colerain is my favorite as I do use them the most. Most customer don't want to go the additional cost of the Getz or the Rice but want a swamped barre so the Colerain come in the picture. I have had wonderful success with them.
IMHO, All of the name brand barrels will shoot more accurately than than 95% of the shooters can hold.
