Why the answer varies
The likely winner depends on the cards a person carries, the merchant category, active bonus categories and offers, reward values, earnings caps, known fees, and issuer terms. Card acceptance can also remove an otherwise higher-earning option. A public guide is a general comparison until a user provides their own wallet.
Pikt personalizes each estimate to the cards you already carry, the purchase details, and any reward values you set. It compares supported earn rates, eligible offers, caps, and card constraints, then explains the result. Use Card Check for a recommendation based on the cards you carry.
Why the usual card can earn less
Platinum holders often default to Platinum for everything because of the prestige — but Gold earns 4× more on dinner.
