Speaking as a non-expert, I think Pix has much bigger scope. Pix is account-to-account. One can buy real estate, pay bills, make person-to-person and business-to-business transactions, government payments, recurring payments. The funds also settle instantly.

Most people don't experience the full scope of Pix which is impressive.

The credit card companies really missed the boat here to become the standard for consumer to consumer payments. Of course, from their perspective, they know that people would not accept having to pay for this service so the companies won’t go near it.
