The reason is that slipping lets you keep the fuselage pointing straight down the runway through the whole final approach, which in turn reduces your chance of a ground loop. With models, as Harry says, crabbing is much, much easier. (It's not because models fly differently than full-sized planes, its that when you're sitting in the cockpit you can know exactly what your bank angle is and you can tell, much better than with a model, if you are lined up straight.)
