While the Delta SkyMiles Gold stands out in terms of the frequent flyer benefits you get, the Amex Gold offers a better earning rate on everyday purchases and more flexible rewards. Note that if you haven't had these cards already, you could potentially sign up for both and get the best of both worlds.

Choosing between Delta SkyMiles and Amex Membership Rewards (MR) points depends on whether you value airline loyalty or ultimate flexibility. In 2026, Amex points are generally considered "better" because they are a versatile currency; you can transfer them 1:1 to dozens of partners, including Delta, British Airways, and Hilton, or use them to book any flight via Amex Travel. This flexibility protects you from devaluations in a single program. Delta SkyMiles, conversely, are a "fixed" currency that can only be used within the Delta and SkyTeam ecosystem. While SkyMiles are often valued lower (around 1.2 cents each) compared to Amex MR points (around 2.2 cents each), they are superior for Delta-specific perks. If you have a Delta Amex card, you get benefits like "TakeOff 15" (a 15% discount on award flights), free checked bags, and priority boarding. Essentially, if you want a "catch-all" luxury travel card with the highest redemption value, stick with Amex points. If you are a die-hard Delta flyer who wants to earn Medallion status faster and enjoys specific "in-flight" savings, then accumulating SkyMiles through a co-branded card is the more strategic move.
