The advantage of the wire clamps is that they have the right amount of tightness. No guessing on how hard to turn the nut driver. Also, they eliminate the need to go back over clamps installed on new hose to tighten them a bit after the hose shrinks. But yeah, I don't like them either. I think some of them are installed at the factory when the sub assembly engine, trans, subframe is not in the car. Then, once in the car, they are at the wrong location to get pliers onto.
