When I got my replacement S4, I cloned it to the first one I had personalized to my liking, in two long steps. The first step was with Kies, having previously done a back-up of the original S4. The second step was manually. I had diagramed what apps. I had and where they were located on their page. no question, it took me a number of hours to totally get the new one to be a clone of the first one.
Your right though, there's nothing like the ease and effectiveness of iTunes to clone a new or restored iPhone to its back-up phone.
