"Best" is rarely a clear cut answers. There is pretty wide variation in the several billion people on the planet. Some have serious side effects, others have none. Some drugs work well as part of a cocktail, but not as stand alones. This idea of selecting a single best option and making everything relative to it would have a strong adverse impact on the market. It would be like saying we shouldn't clear a Ferrari when a Corolla can get groceries just fine at a lower cost.
