I feel like the as a family investment I want a ride that does more with a smaller ride vs less with a larger ride. For example I would way rather have something comparable to space mountain than a slower smaller b&m wing. Part of the reason I consider Tower of terror one of the greatest rides ever made is the fact that it found a way to be thrilling for everyone yet have a low height requirement even compared to other higher height requirement rides. Any park that would nail something like that I think would see huge returns.
