I can't see it from here. I don't know how far it is from the door to the driveway. If you swear you will never want to move something on wheels along this route, go with the steps. Make your steps exactly the same for risers and treads, or you create a trip hazard.
Pour the bottom step first, then frame around it for the next step, and so on.
Otherwise, if you ever think you will take your lawn mower or garbage cans or what have you down that path, go with a sloped path.
