If you like cash back and use often for dining/entertainment, I enjoy my Cap One Savor Card. I'm grandfathered in to 4% cash back on dining/entertainment with no annual fee. I think that option now has a fee, but there's a 3% on dining/entertainment option with no fee. Also has a 3% cash back on grocery, and 1% on everything else.

Travel cards are good too. Lots of good websites out there that compare cards which I have found helpful.
