Well, when compared to its most obvious contemporary - Star Wars: Rogue One - the biggest difference I can divine is that while Rogue One is essentially telling a story we can broadly infer and know will succeed it was at least an important, nay pivotal, event that has enough meat to tell a decent story of its own.
Fantastic Beasts (which I'll throw my hands up to not having seen) on the other hand has only a tangential connection to the broader Harry Potter story. A movie about Dumbledore and Grindelwald or the original Order of the Phoenix that ends with the death of James and Lily Potter would probably have been better received.
