The Discover it Chrome and Discover it Cash Back cards both entice with no annual fees, cash back rewards and introductory APR offers. The Discover it Cash Back edges ahead with its higher rewards rate in rotating categories, ideal for those who don't mind keeping track of these changes.
However, the Discover it Chrome is beneficial for those who prefer consistent rewards on gas and dining without tracking rotating categories. Both cards are strong contenders, but your choice may depend on whether you prefer simplicity or maximizing rewards.
