I have tried many credit cards but I always come back to Discover. The cash back option and the rate at which I can accrue points is great. I especially enjoy the additional money I get when getting rewards with their cashback partners like Chili's, Lowes, Ace, Kohl's, etc. I use Discover whenever I can. They are excellent on security and call me whenever there is any suspicious activity.The only downfall is that it is not accepted everywhere.
