The most unavoidable part of the flight is the landing. If you can't land smoothly, then chances are you are either going to tear up airframes, motors, or props (or some combination of).
Though some takeoff problems have been mentioned with high wings, from my personal observation, high wings are a little easier to land. Less chance of dragging a tip, and they do not appear to bounce as much. You have a much better chance of doing well, if your equipment makes it to the end of the event unscathed........
