Both the Citi Custom Cash® Card and Citi® Diamond Preferred® Card offer attractive features with no annual fees and introductory APR offers, making them strong contenders for anyone looking to optimize their credit card usage. If you're leaning toward maximizing cash back rewards, the Citi Custom Cash is the superior choice with its 5% cash back on your top spending category.
But if you’re focused on managing existing debt, the Citi Diamond Preferred stands out with its extended 0% APR period for balance transfers. While the Citi Custom Cash may not offer a rewards program, its introductory APR offer on balance transfers and purchases is a notable benefit that could still make it a valuable card for your wallet.
