I use credit for the purchase protection (I believe many debit cards have this as well but it’s easier when you haven’t yet paid the charge, and seems better enshrined in law for credit), for the rewards (which including signup bonuses can be huge), for the float period, and for security — if somebody fraudulently uses a credit card versus a debit card, there’s no actual money missing while the situation gets resolved.
Every time I had issues with fraud it was with a cc. The fraud protection is just bandage for an inherently unsafe system that you are paying for yourself.
That being said, I do get that for US individuals it is completely rational to use cc's. I would do that too. If you are paying 3% Visa/MC tax anyway, then you might as well use their perks.
What smelendez is alluding to is the matter of who is liable while fraud is being resolved.
In the US, a charge on your bank card results in at least a hold on your bank account - money you can't spend on anything else until the hold is lifted. Worst-case, there can be significant fees associated with this (overdraft, declined payments, etc.).
For most of us, that's a much bigger problem than a debt we may or may not end up paying interest on.
From personal experience, getting a credit card company to quickly resolve fraud cases is also much easier than getting a bank to do the same, even when it's ultimately the same institution.
