People often debate on whether to get a miles card or a cashback credit card. However, both credit cards have strengths and weaknesses. For instance, some miles cannot be directly redeemed for cash and are worth less than cashback points. On the other hand, SkyMiles are more valuable than cashback points when redeeming Delta flights, so travellers prefer it. 

For many cardholders, it could be more advantageous to have both for different circumstances.
