I read somewher that stainless barrels......esp from big manufacturers tend to be higher quality ....than their regular barrels. so for that reason they may be worth it, higher quality, better accuracty etc.....

my favoriteis stainless coated black......not sure why more stainless are like this.....but depends on the gun/caliber, where its used etc.....but ya if they are better barrels, that alone is a good reason to get one.
