If you travel internationally you need both Visa and Mastercard, I agree. Personally I feel everyone should have 3 cards, a Visa a Mastercard, and one other (any network). And make sure they are from at least two different banks, just in case a fraud alert on one card, shuts down the sibling card from the same bank. For best safety keep the 3rd card at home, and rotate it every month or two (don't go over 3 months though) with one of the other cards - that way if your wallet is stolen you still have something available at home.
