Perks, credits, and redemptions
| Perks | American Express® Green | Discover it® Cash Back |
|---|---|---|
| Lounge access | None | None |
| Annual credits | ~$199/yr (1 credits) | None |
| Points & redemptions | Transferable to airline & hotel partners | Cash back only |
On perks and redemptions, the American Express® Green carries the heavier credit stack (about $199 a year); the American Express® Green earns transferable points with a higher redemption ceiling, while the other is capped nearer a flat cent. Weigh those against the fee, since credits and lounge access only count if you will actually use them.
Transfer partners and point value
Only the American Express® Green earns transferable points. Its Amex Membership Rewards move to Delta, ANA, Air France-KLM Flying Blue, Virgin Atlantic, plus Hilton and Marriott, where a point can be worth several cents on a premium-cabin redemption, far above its cash value. The Discover it® Cash Back pays flat cash back, worth about a cent, so its ceiling is nearer a penny per point no matter how you redeem.
Different rewards philosophies: the Green earns transferable travel points for a fee, the Discover it earns free cash with a rotating 5% and a first-year match.
The Green suits a traveler who values Amex transfer partners and 3x on travel, dining, and transit. The Discover it is a free everyday card whose rotating 5% and Cashback Match can effectively pay 10% in bonus categories. Paid transferable points vs free rotating cash.

The verdict
If you travel and value transferable points, the Green earns well into the Amex network, though $150 asks for real travel and transit spend to justify past year one.
If you want free, high-value everyday cash, the Discover it Cash Back is hard to beat, rotating 5% plus a first-year match with no fee. For most people who won’t lean on the Green’s travel categories, the free Discover it delivers more usable value. Travelers lean Green; everyday spenders lean Discover it.
