These two rides are so different that its hard to compare the two against each other. RnR is more intense in the fact that its faster, the beginning launch part at the beginning looks really intimidating when watching it in line, plus it does have loops. I personally have no problems at all with RnR and find it really fun to ride. EE is a slightly more traditional coaster with a hill/drop, twist and turns. The most intense part of this ride is the backwards section. This part takes my stomach worse that any other part of either ride and makes me a bit anxious. If I had to choose between the two, I would ride RnR before I would EE. If I was including Space Mtn on this list, I would ride that one last because I don't care for all the little dips/drops. I think that you have to weigh what about the coasters bother you (or your DD) and make a decision based on that.
