Both the Citi Custom Cash Card and the Bank of America Unlimited Cash Rewards Credit Card offer enticing cash back rewards without the burden of an annual fee, coupled with introductory APR offers. The Citi Custom Cash edges ahead due to its higher cash back rate in your top spending category, making it a compelling choice for maximizing rewards.
However, the BofA Unlimited Cash offers 1.5% cash back on all purchases, which could be more beneficial for those who prefer a straightforward rewards program without the need to track spending categories.
