i think freddy is the grand champ, he uses some twisted shit to kill you like rip your veins out and use you as a puppet or melt you to a motorcylce, i mean its like torture death, jason just kinds of puts you out of your misery before it starts , but hes had his killings aswell i mean being impaled up the ass and turned into a shisk-ka-bob would ruin your day my favorite though is the Sin killer from Seven he put some serious thought into his shit
