Bilt Obsidian vs Bilt Palladium

Every figure below is from the same dataset Miles computes its recommendations from. Rows the two cards agree on are collapsed at the bottom.

Economics

Dollar figures are per year unless the row says otherwise. Ongoing annual value is Miles' estimate of what the card adds per year after its annual fee: statement credits discounted for realistic use, benefits, and earning above a strong flat-rate card on a typical spending profile. First-year value is a separate net figure that includes the welcome bonus. A welcome bonus shown at its advertised maximum may not be available to every applicant; that figure is not marked as stronger. ★ marks the stronger comparable figure on other rows, and no row is marked when either figure is unknown.
Figure	Bilt Obsidian Column N.A.	Bilt Palladium Column N.A.
Annual fee	Best: $95 $400/yr less	$495
Ongoing annual value, after fee	$368	Best: $416 $48/yr more
First-year value	$343	Best: $866 $523/yr more
Authorized user fee	Best: $50 $45 less	$95

Sign-up Bonus

The current welcome offer as recorded in the dataset. No winner is marked: a bonus is points times a valuation times a spend requirement you may or may not clear, and the first-year value above already prices it.
Offer	Bilt Obsidian Column N.A.	Bilt Palladium Column N.A.
Current offer	$200 Bilt Cash when you apply & are approved	50K Bilt points + Gold elite status after $4K non-housing spend in the first 3 months + $300 Bilt Cash

Earning

Percentages are the return on a dollar spent: the multiplier times what Miles values those points at. ★ marks the higher return on a row. Categories only one card earns a bonus on are marked for that card; the other earns its base rate.

Benefits

Statement credits, lounge access and elite status as listed in the dataset; protections are counted, not listed. No winner is marked: twelve small credits are not more than two large ones, and the row that prices them, ongoing annual value, is under Economics.

Which one is right for you

This page shows the difference. It does not pick: the winner depends on what you spend and what you already hold, and adding these figures up without knowing that would be a guess dressed as a verdict. Ask Miles and it computes the answer against your own wallet.
