The verdict
On a typical year of household spending, the American Express® Blue Cash Preferred earns about $679 a year in rewards and the Delta SkyMiles® Platinum about $382, valuing every point at a flat 1 cent. The American Express® Blue Cash Preferred charges $95, but carries about $84 in annual statement credits that offset it for anyone who uses them. The Delta SkyMiles® Platinum charges $350, which you clear through its rewards and perks. Counting rewards, fees, and any credits, the American Express® Blue Cash Preferred delivers more total value, about $595 a year more for a typical spender, mostly because it earns more where you spend most, on groceries and gas. Neither leans on transferable points, so the deciding factors are the welcome offer, the card network, and which everyday perks you will actually use. On the sign-up bonus, the Delta SkyMiles® Platinum currently has the larger welcome offer (a limited-time offer above its usual amount, so treat it as a one-time boost). A welcome bonus is a one-time event, so weigh it apart from the ongoing rewards.
Pick the American Express® Blue Cash Preferred if your spending leans toward groceries, gas, streaming. Pick the Delta SkyMiles® Platinum if your spending leans toward dining.
