I struggle to maintain loyalty to a specific toothpaste variety because of the overwhelming variety of types of Colgates and Crests stocked everywhere in the US. Even when I think I have discovered a variety that tastiest pleasant and seems to be effective, the next time I find myself in front of the shelf I struggle to recall the details: was it cool mint with gum protection? Or fresh mint with whitening? The packages seem to change subtly every few months and it's not clear that every store stocks the full range so I frankly have no idea whether I am sticking with the same toothpaste over an extended period.

My favourite example of this going too far was a toothpaste sold in "day" and "night" formulations, but their Canadian Drug Identification Numbers were the same. Ie: identical products in different packaging.
