it Cash Back
The most generous first-year card - if you can remember to activate the categories.
The first-year cashback match is the most generous welcome offer in the category, full stop - there is no spend-by-three-months pressure, no minimum, no asterisk. The 5% rotating categories require you to remember to activate them quarterly, which is the friction. If you are willing to set a calendar reminder four times a year, this card pays you twice for the same purchases for twelve months. Then it becomes a respectable backup card.
Who it's forBuilding or rebuilding credit, comfortable with quarterly category-activation, doesn't want to pay an annual fee.
