Both the Credit One Bank Platinum X5 Visa and the Costco Anywhere Visa Card by Citi offer cash back rewards. However, the Costco Anywhere Visa edges ahead with its higher cash back rates on gas, travel, and dining and no annual fee structure, provided you're already a Costco member.
The Credit One Platinum X5 is more accessible with its lower credit score requirement and also offers a robust 5% cash back on select categories. If you frequently shop at Costco, the co-branded Costco Anywhere Visa could yield the most benefit. Yet, for those with lower credit scores or who value flexibility in credit requirements, the Credit One Platinum X5 remains a worthy option.
