The best credit card for people who pay their balance off every month
The answer for this question varies from person to person. However most cards give lousy rewards percentage-wise. Take a look at where your money is being spent each month (say with a tool like mint.com), and seek out a card that rewards you in categories where you already spend a lot of money.  Many people here have suggested cards with high gas rebates, and that's great if you drive more than anything else. However, the important thing is to pick what benefits you most.
