I think the Alicuberre drive is worse because it’s expensive science working on a project that violates known scientific principles in multiple ways. At minimum LLM has some good uses in business and to create boiler plate journalism. It might turn into something more eventually. Alibucurre drives can only end in futility because none of the stuff proposed can exist. Negative mass and negative energy are fiction. The theory of relativity closes off FTL travel and must do so to preserve causality.
