I have two chip and signature cards that I love... CitiForward and Citi ThankYou Premier.
CitiForward gives me 5 points per dollar on restaurant and Amazon purchases, and the ThankYou Premier card gives me a point per dollar spent, plus a point per mile flown with tickets purchased on the card, plus has no fx fee. These points go into the same account, and I can redeem them for plane tickets at the rate of 1 point = 1.33 cents, so in essence I end up getting 6-something % back on restaurants and Amazon, and a flight to Europe (for example) gets me around $133 towards flights. It adds up quickly.
