The verdict
On a typical year of household spending, the Delta SkyMiles® Platinum earns about $382 a year in rewards and the Marriott Bonvoy Brilliant® about $544, valuing every point at a flat 1 cent. The Delta SkyMiles® Platinum charges $350, which you clear through its rewards and perks. The Marriott Bonvoy Brilliant® charges $650, but carries about $335 in annual statement credits that offset it for anyone who uses them. Counting rewards, fees, and any credits, the Marriott Bonvoy Brilliant® delivers more total value, about $30 a year more for a typical spender, mostly because it earns more where you spend most, on everything else and travel. 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 Marriott Bonvoy Brilliant® 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 Delta SkyMiles® Platinum if your spending leans toward groceries. Pick the Marriott Bonvoy Brilliant® if your spending leans toward dining, travel, everything else.
