Visa = MC for Debit cards. Also, you do have fraud protection on the debit cards as well. Also, they can be run as credit cards. I always have my debit card ran as a credit card. My bank (asshats they are) charge if theres more then 10 debit card purchases a month. But, I get unlimited CC purchases, even if its with my debit card. So, get the debit card, use it as CC and dont pay the dumbass penalties for too many DC purchases a month.
Thats my experience anyways.
