I second Pure Blues.Recommend DR Pure Blues, my new go-to nickel round. Lovely round tone with some bite and nothing that annoys me.
I do love Dunlop Superbrights. But I had way too many occurences of the same quality issues. I switched to Pure Blues for my most recent restring and I am very happy. They have a nice boldness to them, throughout the tone range. Big lows, cool high mid grind. Great rock string. But they also warm up REAL nice, when they age. They also have fantastic note definition and balance, from string to string. I got the pack with the .130 B and it is the best B string I have ever used. Positive feel, clear notes. Good punch.
