Credit Card only - never ever Debit.
I had my CC compromised more than once at a gas station (once by the cashier) where the bank locked my card (MC) and called me - even in the middle of the night. They even call when I use my card for unusual transactions or in not (for me at least) common locations. I apparently bought 7 iphones last week, got a phone call at 10:30pm and the charges were immediately reversed. Peace of mind - priceless.
When your debit card gets skimmed you're screwed big time, that money is gone for good.
The only drawback is, you never want to miss a payment once.
