The card offers increased rewards for selected purchases and 1 point for all other purchases. For example, it offers 5X points on select Mercedes-Benz purchases, 3X points on gas stations, 2x points at restaurants and 1 point everywhere else. So, depending on whether you spend enough on therse types of purchases this card may or may not be beneficial for you. The 5X bonus is ok when you spend a lot on Mercedes purchases, and it may turn out great if you are planning to buy or lease a car or buy some accessories, but check first if you are able to charge a car to your credit card. The credit limit may not be enough for big purchases.
General rewards credit cards, however, may bring you rewards for any purchases, and these rewards can be easily redeemed and never expire.
