Verdict
Our Pick: Citi Custom Cash Card
With a 4.5/5 rating, the Citi Custom Cash Card edges out the Southwest Rapid Rewards Plus (4.2/5). No annual fee makes it easy to justify. The Citi Custom Cash automatically gives you 5% back on whichever eligible category you spend the most in each billing cycle. No sign-ups, no rotating — just spend and it adjusts.
