Ketchup is personal choice. Some like ketchup, their choice. I will grab BBQ sauce personally over ketchup for my hotdogs. But it comes with understanding adding either is adding flavored sugar onto the food.
I do that sometimes too for Hot-Dog. Actually Hot-Dogs are something i "vary" a lot with. Sometimes its just Ketchup, sometimes its just sauce, sometimes its Ketchup/Mustard, sometimes its simply Cheez-Wiz (when i have some at home, wich is not often, but every once in a while i buy one).
I can't eat "Tourtiere or Paté Chinois" without a ton of Ketchup personally. But with it, its something i really like.
I knew a guy who would put Mayonaise on Pizza and Steak... so yeah different taste for everyone
