People have posted photos of some down right beautiful airplanes using a variety of covering methods. I myself have been using a lot of Koverall lately BUT I think we are missing an important point. OP sounds like a fellow who is doing his first covering job. Unless he has a local mentor to help out (would he be posting here if he did?), a lot of the planes shown would be pretty intimidating. If this is the first covering job that he is attempting I would suggest keep it simple. Stick with iron on plastic covering and peel and stick graphics. It is easiest to apply and easiest to repair with a higher probability of actually making it to the flight line.
