I have Discover It and it's pretty cool. When I signed up they were doing a promotion (pretty sure it's still going on?) where new card members get Cashback Match on all the cashback they earn, so whatever you earn throughout the year they give that same amount back to you after your first year. Can do it as statement credit, direct deposit, or gift card. Their 5% bonus categories have been pretty good this year. I've had the card since April and already have earned over $250. I use my card a lot though.
