To pick the winners, MONEY and NerdWallet evaluated more than 2,200 current credit card offers, focusing on rewards, fees, introductory and regular APRs, sign-up bonuses, and other, more specialized perks. For each category, MONEY set parameters for what constituted a winner, and NerdWallet scoured its database to find candidates, disclosing to MONEY any issuers from which it receives compensation when people apply through its site. MONEY then independently compared and fact-checked the cards and made the final decisions. —Taylor Tepper
