The Capital One Quicksilver Cash Rewards Credit Card and Capital One QuicksilverOne Cash Rewards Credit Card both offer unlimited 1.5% cash back on all purchases, making them attractive for straightforward earning potential. However, the Quicksilver card is slightly better due to its 0% introductory APR period on purchases and balance transfers, but requires excellent credit.
The QuicksilverOne card has a lower credit score requirement, making it more accessible. However, it has an annual fee and does not offer an introductory APR offer.
