“A Bezos Moat is premised on the idea that the customer is willingly and is frequently entering into a commercial transaction with the company because the customer is deriving more value from the transaction than he or she is paying for.
“A Buffett Moat attempts to identify companies that will be the only one (or one of a few) available in a commercial landscape, so that the customer is, in effect, forced to transact with these companies (i.e. only bridge, only newspaper, only soft drink option).”
