Just adding more fuel to the fire between the two :]
I don’t have a lot of experience as a jeweler, but I think many of the differences are nit-picking for personal use (how we work) rather than the customer. I only say this because the average consumer seems to care if it’s true silver or plated and not what grades are available. The fact that one or the other may have better tarnishing effects etc etc etc etc is just an added bonus that “most” people don’t even consider. Of course, this may not be true for high-end jewelry.
