To be honest, I prefer unique names to those that are repeated at different parks. I can see the press appeal to chain parks like Six Flags and Paramount, though, because those sorts of names will attract people that are familiar with the similarly named coaster at their home park. But if I recall, some parks (CP at least) trademark names: Raptor and Millenium Force both, and I don't know what else.
