The verdict
On a typical year of household spending, the American Express® Green earns about $402 a year in rewards and the Bilt Obsidian about $490, 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 Bilt Obsidian charges $95, but carries about $300 in annual statement credits that offset it for anyone who uses them. Counting rewards, fees, and any credits, the Bilt Obsidian delivers more total value, about $193 a year more for a typical spender, mostly because it earns more where you spend most, on groceries. Both earn transferable points rather than flat cash, so the deciding factor is whose transfer partners reach the airlines and hotels you would actually book. On the sign-up bonus, the American Express® Green currently has the larger welcome offer. 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 travel. Pick the Bilt Obsidian if your spending leans toward groceries.
