Top barrels for LR/1k are shilen, hart, lilja, spencer, k&P, border, krieger. Yes there are others, but these are the most common. If I forgot someone's favorite, sorry.
Some are favored more in certain disciplines. For example Highpower shooters like Kriegers. Short range BR favor shilen, hart, lilja and spencer.
Does not mean others are not good, just that the shooters and gunsmiths have learned how to set up guns (very well) with those barrels for that particular discipline. They feel more confident with those barrels.
