Every rewards program has a loyalist ready to explain why their currency is the real one. The honest answer is more boring and more useful: it depends entirely on redemption, and most people redeem badly enough that the debate barely matters.
The three currencies, priced
Cashback is worth exactly what it says: one percent is one percent, credited automatically, no calendar, no availability. Points and miles are variable-value currencies — worth fractions of a cent in bad redemptions and multiples of a cent in good ones. That spread is the entire game.
- Cashback: fixed value, zero effort, the reliable floor
- Points: flexible, transferable, best with airline partners at premium cabin rates
- Miles: strongest for long-haul premium seats, weakest for anything domestic and short
The math on the ground
A flat two percent cashback card returns a two percent discount on your spending, forever, automatically. Premium travel cards earn points that clear two percent only in the redemptions most people never make — premium cabin international awards booked with transfer partners, at the front of the plane the program is actually designed to sell you. Transferred to a mediocre redemption, the same points are worth one percent. The difference is not effort; it is knowledge, and it is a real second job if you let it become one.
How to choose, honestly
Choose cashback if you will not learn redemption games — or value your weekends. Choose transferable points if you fly long-haul in the front cabin and enjoy the planning as much as the seat. Never choose an airline-specific currency as your only card: single-airline miles devalue on the airline's schedule, and the airline's schedule does not include your travel plans.
And whatever you choose: the redemption rate is the only score. A reward you never redeem is an interest-free loan you made to a bank, denominated in a currency they can print.
