Certainly! Both are arguably the best coasters on their properties, with Mummy passing Rockit, in my opinion, based off consistency in smoothness. Mummy was the best air time machine in Florida (save for Dania Beach Hurricane) before Cheetah Hunt and Mako came.
Everest's backwards section is quite forceful and a unique experience compared to any ride I've ever been on. Paired with a fantastic drop, excellent pacing, and one of the best themed experiences Disney has ever created I always rated it quite a way higher than RnRC's fairly plain layout. Not that I don't love RnRC, of course!
