Guide
Which Amex card should you use and when? (2026)
By the Pikt editorial teamPublished Updated
Pikt tells you which card to use
Most card lists rank cards you could open. Pikt compares the cards you already carry for this purchase, then shows the estimated dollar difference and why the recommendation fits.
This is personal card routing: match each purchase to the right card from your wallet. Pikt recommends the card; you still pay with it yourself.
The general answer, before your wallet
Amex Gold covers dining and groceries at 4×. Amex Platinum adds lounge access and hotel status but earns 1× on most spend. Blue Cash Preferred targets 6% groceries and 3% gas for cash-back fans.
Quick decision table
| Card | Best for | Earn rate | Annual fee |
|---|---|---|---|
| Amex Gold (opens in a new tab) | Dining + groceries | 4× points | $325 |
| Amex Platinum (opens in a new tab) | Perks + travel | 5× flights | $895 |
| Blue Cash Preferred (opens in a new tab) | Cash back | 6% groceries | $95 |
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 learns from confirmed card choices over time, while verified rewards math remains the basis for the result and the explanation. 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× on dinner to Platinum's 1×.

Enter the store and amount. Pikt estimates which card in your wallet is likely to earn the most. It shows the estimate of each card’s rewards and a short reason. Issuers decide the final rewards. Online, Pikt Checkout shows this estimate before you pay. For recurring bills, Subscriptions compares the cards you already carry and explains how to change the card on file. In a store, run Card Check on your phone before you pay. Pikt counts any Amex Offer that Pikt knows about on your cards, then estimates whether Gold, Blue Cash, or Platinum is likely to earn more by category.
