I enjoy both but Hulk is more of a standard coaster after the launch, just with onboard music. It has bigger thrills and I love the first half, but it's nothing too special for a theme park after that. Mummy, while not as big, has great theming throughout. I like the dark ride opening and the coaster section is a lot of fun. Plus with it not being as intense as Hulk I can ride it over and over. Hulk I need a break between
