High scores are more fun than low scores!
I have Beretta O/U field and sporting clay guns and the best scores that I ever shot at trap were with a borrowed Kriegoff unsingle. For me the high rib makes it easier to focus on the target. I still couldn't shoot a straight .
I will agree that you can shoot trap with any kind of gun and you can enter a mule in a horse race but the chances of doing good at anything without the proper equipment are slim and none. Larry
