The Bilt Obsidian Card costs $95/yr — that's $95 more than the Joss & Main Mastercard (no annual fee). To justify that gap, you need to extract at least $95 in annual value from the card's higher earn rates and benefits.
Bottom line: Use the year-one vs ongoing table for modeled earn value at your spend level. The $95 fee gap means the Bilt Obsidian Card needs roughly $95 more in annual rewards (or credits you will use) to break even on dining and grocery stores and everyday spend.
