Both the Citi Custom Cash and the Discover it Chrome offer enticing rewards and introductory APRs. The Citi Custom Cash edges ahead for its higher cash back rate in your top spending category. But if you're eyeing a longer balance transfer offer, the Discover it Chrome's 18-month period is noteworthy.
Neither card charges an annual fee, and both require good to excellent credit, keeping them on equal footing for accessibility. While the Citi Custom Cash may be the frontrunner for cash back, the Discover it Chrome's longer intro APR period for balance transfers is a compelling feature if you’re looking to manage debt.
