Editorial take: American Express Green Card

Hard to justify vs. Chase Sapphire Preferred at $95 with stronger earning. The CLEAR credit is nice but only useful if your airport has CLEAR lines. Most people are better off with Sapphire or Amex Gold.

Editorial take: Discover it Cash Back

The first-year Cashback Match effectively doubles your earnings, someone who earns $300 in cash back gets $600 total. It's the best no-fee first card for building credit with real rewards.
