Both the Credit One Bank Platinum Rewards and the Discover it Chrome offer cash back rewards and waive annual fees. If you're leaning towards balance transfer opportunities, Discover it Chrome emerges as the better option with its 0% introductory APR on purchases and balance transfers.
However, for consistent cash back on various purchases, the Credit One Platinum Rewards card is a good choice. While neither is a co-branded or store card, the Discover it Chrome's introductory APR offer and lack of foreign transaction fees give it an edge for those planning to manage existing debt or travel abroad.
