yes, the royal crown is higher. The store I am purchasing from recommends the x prong. When I saw both, I felt that the x prong is sturdier, with stronger prongs, while the rc is more delicate and thinner. Also, the prongs on the rc that I was shown were not spaced well, almost misaligned. Until I saw both, I had my mind made up on the rc, but now I am not sure. When I was at the store, I asked a woman which one looked nicer and she picked the rc. It's so hard to decide!
