For a long time I resisted using step drills. I don't even remember why. But I am glad that I've put that behind me, 'cause every workshop needs them. I used drill bits and spade bits in the past to create holes and depending on the material, they might be decent, or they might be a disaster. Step drills make beautiful holes, nice and neat and clean. These are especially useful because of the quick-change 1/4 inch shank.
