What are the differences between the Chase Freedom Flex and Freedom Unlimited credit cards?

The Chase Freedom Flex and Freedom Unlimited credit cards are both popular offerings from Chase, but they differ in their rewards structures. The Chase Freedom Flex card offers a combination of rotating quarterly categories where users can earn 5% cashback on up to $1,500 in purchases, as well as 3% cashback on dining at restaurants and drugstore purchases. On all other purchases, it provides 1% cashback. In contrast, the Freedom Unlimited card simplifies earning by providing a flat rate of 1.5% cashback on all purchases without any spending caps or rotating categories. Both cards offer additional benefits such as a $0 annual fee, sign-up bonuses, and intro APR periods, but their appeal depends on a user's spending habits, with the Freedom Flex being more advantageous for those who maximize the rotating categories and the Freedom Unlimited favoring those who prefer consistent rewards across all their spending.
