Recommend me a credit card

Background: I currently have a TD Rebate Rewards VISA and have been using it actively for 4 years now. I have never missed a payment and my current limit is $2500. I recently graduated from university and am currently working full-time. Now that I am making and spending more money, I am wondering if there is a superior credit card I could get to take advantage of better rewards. I currently bank with TD as well and I'm not looking to switch for a larger credit limit - I'm simply interested in better rewards.

Thanks for your help!
