What are the best balance transfer credit cards with rewards?

The best balance transfer credit card with rewards is the Discover it Balance Transfer card, because it offers 0% APR for at least 15 months on balance transfers paired with a 3% balance transfer fee, and it offers above-average cash back rewards that won't lose value. On top of that, the card doesn't charge an annual fee.

The Discover it Balance Transfer card's 18-month 0% APR period on balance transfers is longer than average, and the card offers 5% cash back on rotating quarterly categories like gas and grocery stores, up to a quarterly maximum. You will have to register every quarter, though. Past that, it gives 1% back on all other purchases. It has a nice anniversary perk, too: Discover doubles all cash back earned in the first year, automatically, with no limits.
