Both the PenFed Power Cash Rewards Visa Signature® Card and the Costco Anywhere Visa® Card by Citi offer enticing cash back rewards, making them strong contenders for anyone looking to maximize returns on their spending. However, if you're a frequent Costco shopper, the Costco Anywhere card is better for its higher cash back rates on gas, travel and dining and additional rewards for Costco purchases. It's a co-branded card that requires a Costco membership, which could be a significant advantage for loyal customers of the warehouse club.
On the other hand, the PenFed Power Cash Rewards card has a welcome bonus and the potential for high cash back rewards across all purchases. It's a solid choice if you prefer a card without a specified credit score requirement or you're already a PenFed Credit Union member.
