Why there are several: the undated name can move to a newer build when the developer updates it, while a dated snapshot is meant to stay fixed, which can suit pipelines that need repeatable behaviour; an experimental build tests new features. Sellers price each version separately and not every seller offers every version, so check a seller's own docs for the build it serves.
