The verdict
On a typical year of household spending, the American Express® Green earns about $402 a year in rewards and the United℠ Gateway about $320, valuing every point at a flat 1 cent. The American Express® Green charges $150, but carries about $199 in annual statement credits that offset it for anyone who uses them. The United℠ Gateway has no annual fee, so its rewards are all profit. Counting rewards, fees, and any credits, the American Express® Green delivers more total value, about $31 a year more for a typical spender, mostly because it earns more where you spend most, on dining and travel. The bigger difference is the ceiling: the American Express® Green earns points you can move to travel partners for outsized value, while the United℠ Gateway stays locked to a single airline or hotel program. Favor the American Express® Green if you will use travel transfers, the United℠ Gateway if you want simplicity. On the sign-up bonus, the two are currently comparable in size. A welcome bonus is a one-time event, so weigh it apart from the ongoing rewards.
Pick the American Express® Green if your spending leans toward dining, travel. Pick the United℠ Gateway if your spending leans toward gas.
