Busch Gardens (at least for the most part) has always done so much more with their coasters than Six Flags. They don't usually do the first of any coaster, but instead take it to the next level figuring out how to make it the best it can be to fit in the existing park, interacting with existing elements like the train and the walkways and incorporating animals. I grew up going to Six Flags Great Adventure in New Jersey and I've been to many of their parks, and they all have moments of being great, but Busch Gardens always takes the concept to the next level, spending more on development of the ride rather than just buying something "off the shelf" and plopping it onto a piece of land that it fits on. Six Flags tried to take their parks (or at least some of them) to the next level spending huge sums of money trying to make them more like Busch Gardens and they ran up $2 billion in debt and had to go into bankruptcy.
