Both the PenFed Power Cash Rewards Visa Signature® Card and the USAA® Cashback Rewards Plus American Express® Card offer compelling cash back rewards without annual fees, appealing to savvy spenders. However, the PenFed Power Cash Rewards edges out slightly with a higher cash back potential for PenFed Honors Advantage Members and a lower required credit score, making it more accessible.
The USAA Cashback Rewards Plus offers up to 5% cash back in specific categories, but the lack of a welcome bonus and a higher credit requirement might limit its appeal. Still, this card's targeted rewards are worth considering for those who frequently spend at gas stations and military bases.
