Citi Double Cash vs Discover it Cash Back
The clean 2% flat card versus the 5%-rotating card with a first-year twist. The Double Cash earns 2% on everything (1% when you buy, 1% when you pay) with no categories to track. The Discover it Cash Back earns 5% in rotating quarterly categories (up to $1,500/quarter, activation required) and matches all your cash back at the end of year one. Simplicity versus engagement — and a big year-one kicker.
Citi Double Cash
Readers who want one flat-rate no-fee cashback card and aren't interested in tracking categories. The 2% (1% at purchase + 1% at payment) is the cleanest math in the cashback space.
Discover it Cash Back
First-card or rebuild-tier readers who want a $0 AF card with rotating 5% categories and Discover's year-one Cashback Match. Customer service is the best in the industry.
Pick Citi Double Cash if
Set-it-and-forget-it spenders who want one flat rate on all spending
2% on every purchase with no activation, no cap, and no category tracking — the cleanest math in cash back. The only catch: the back 1% credits only when you actually pay the statement, so treat it as a pay-in-full card.
Pick Discover it Cash Back if
Engaged spenders, especially in year one, whose spend aligns with rotating categories
The first-year Cashback Match doubles everything you earn, so year one effectively pays 10% in the 5% categories and 2% on base spend. If you'll activate each quarter and your spend fits the calendar, year one is hard to beat — just re-evaluate for year two, when it's a 5%/1% card.
Skip both if
International travelers. The Double Cash charges a 3% foreign transaction fee, and Discover's acceptance outside the U.S. is spotty even though it charges no FX fee. Neither is the card to pack for a trip abroad.
