The verdict
On a typical year of household spending, the Bilt Obsidian earns about $490 a year in rewards and the United℠ Explorer about $322, 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 United℠ Explorer charges $150, which you clear through its rewards and perks. Counting rewards, fees, and any credits, the Bilt Obsidian delivers more total value, about $373 a year more for a typical spender, mostly because it earns more where you spend most, on groceries and dining. The bigger difference is the ceiling: the Bilt Obsidian earns points you can move to travel partners for outsized value, while the United℠ Explorer stays locked to a single airline or hotel program. Favor the Bilt Obsidian if you will use travel transfers, the United℠ Explorer if you want simplicity. On the sign-up bonus, the United℠ Explorer currently has the larger welcome offer. 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 dining, groceries, travel.
