> Yes, whenever a credit card fraud investigation will be resolved in your favor, so would it be for a debit card – and the outcome is "no money lost" in both scenarios as well.

No, you're assuming the bank is obligated to refund you everything. As I mentioned at the top, this is always the case for credit cards but not necessarily always the case for debit cards.

As this is becoming circular, I don't wish to continue. Enjoy your debit card and I hope you never experience fraud.
