I have a chase freedom card. It's simple, and the rewards are cash--which is the best possible reward, imo. It used to be much better (you could trade in $200 worth of rewards for a $250 check, and you got 3% in whatever your highest categories for the month were, not whatever categories they chose for you), but it's still a solid card. 1% back on everything, 3% on their revolving special categories like groceries, gas, travel, entertainment, etc.
Who cares if the limit is low and the rate is high? If you only charge what you can afford to pay off each month, it's not an issue. I think my limit when I got the card was only $5k, but omg, if I ever charged $5k in a month I would have been in trouble. After 6-12 months I petitioned them to raise the limit, and it's now at $15k, which is waaay more than I should be spending in a month! Every once in a while I'll have a massive bill when I buy plane tickets and a cruise at the same time, but even then it's nowhere near the limit.
