Physically, they're probably about on par, but I would still call Mummy more "intense", personally, once factoring the darkness and the theming. The Mummy's overall vibe is creepy/scary, where Hagrid's is supposed to be fun/adventurous. Being able to see nearly everything on Hagrid's makes it a much more pleasant ride for me, since you can lean into the curves as they're coming up, whereas with the Mummy, I feel a bit more thrown around because I don't know what's happening next.
