Earlier quoted context omitted.
PIX is also better because it gives control back to the central bank (as it was with cash) and not private industry although they are providing the service. The central bank controls what payments are permitted by what laws exist, not some risk management system that has decided that your legal purchase is too risky or some foreign state has applied sanctions against you.
Wero is run by the banks themselves, which are in turn controlled/restricted by the central bank. I don't think there's a meaningful difference on that front. The European ECB isn't really in a position to directly offer services to people, and relying on every country's central banks to cooperate will take decades.
SWIFT is a cooperative of banks also but it seems that some central banks endeavours are better. BTW Argentina created an innovation back in the early 2000s as a product of a crisis. It was implemented in record time and transfers were immediate back then and improving. It's not run by the central banks though.
