Both the Discover it® Chrome and the Discover it® Miles cards offer appealing perks such as no annual fee and generous introductory APR periods. The Discover it Miles edges ahead slightly with a higher balance transfer score and a longer 0% APR period on purchases and balance transfers.
However, if earning cash back at gas stations and restaurants is a priority, the Discover it Chrome's 2% cash back in these categories could sway your decision.
