The verdict
On a typical year of business spending, the Bilt Obsidian earns about $546 a year in rewards and the Ink Business Unlimited® about $675, valuing every point at a flat 1 cent. The Bilt Obsidian charges $95, but carries about $300 in annual statement credits that offset it for anyone who uses them. The Ink Business Unlimited® has no annual fee, so its rewards are all profit. Counting rewards, fees, and any credits, the Ink Business Unlimited® delivers more total value, about $74 a year more for a typical spender, mostly because it earns more where you spend most, on everything else and advertising. 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 Ink Business Unlimited® 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 Bilt Obsidian if your spending leans toward travel. Pick the Ink Business Unlimited® if your spending leans toward advertising, shipping, office supplies.
