I use these strings for a year, the feature that I like most is their strength, I have not broken a string since their adoption.
Well maintained, they keep a good sound / justèce long enough.
The price / quality ratio is excellent.
In electric, I can not compare with the Ernie Ball (I do not really know the other brands), I wanted to test the DR but after trying the D'Addario 010-046 ELX110 I have no intention to look elsewhere.
