Trebuchet or Catapult

Which one is cooler, better, or faster, preferred between you guys? I recently got both Da Vinci models from Hobby Lobby and am interested and how vastly different they are. I prefer the trebuchet, as I think it's a better idea. It revolves around physics and motion laws, instead of tension and that Is interesting to me! What do you guys think is cooler or better or just your general thoughts?
