OK then! Never did consider that. Is wire expensive enough though to make "bad" wire a thing? Out of curiosity, I'm going to order a pack of premium coils next time to compare. They are still very cheap!
There are differences in wires that are labeled the same type. I work in the welding industry and we have customers that will only use one brand of stainless wire or rod because of how it welds which is due to the chemical composition.
