Editorial take: Blue Business Plus from Amex

The silent workhorse of the Amex MR ecosystem. 2x on everything up to $50k/year with no annual fee. Pair it with the Platinum or Gold to unlock transfers, and you have a powerful everyday earner.

Editorial take: Bilt Obsidian

The headline tier of Bilt 2.0, launched February 7, 2026 by Cardless after the Wells Fargo era ended. Strongest for renters who eat out (or buy groceries) and use Lyft. The $100 hotel credit pays back most of the AF if you stay 2+ nights anywhere on the Bilt Travel portal. Pair with the no-fee Blue if you want a no-AF anchor too.
