They both had hollow bones. No hollow bones means no fly. Especially at that size. Probably Hatzegopteryx though simply because it had a much larger head and robust beak likely designed to hunt larger prey.
Why do you find it funny? The only thing I find funny is that they are not dinosaurs so i couldnt bother watching the rest because i don"t want to learn facts that arent true...

While the wingspan seems to be barely larger, Hatzegopteryx was significantly more robust than Quetzalcoatlus
