The difference in salts MIGHT be like

the difference in listening to a popera star and an opera star.

Some people may not be able to tell the difference. Some people claim the opera star is singing better and that you are getting more for your money, and that you are being enriched.

Some people may care about it and others not. Some people may pay for it and others not.
