If you don't want to worry about maximizing categories but do want a rewards card with more rewards power and richer perks than a run-of-the-mill 1.5 percent flat-rate cash back card, then you should consider the Chase Freedom Unlimited. It carries additional unlimited cash back categories and a range of valuable travel protections and partner benefits (including Lyft and DoorDash).Plus, the Freedom Unlimited is a great pick if you already have a Chase Ultimate Rewards credit card, as you can pool your rewards for a higher redemption value toward Chase travel.
