I think you can find plenty of articles on the trade-offs between the two architectures. For Becsy in particular, I wanted all the data structures to be compatible with a lockless multithreading strategy and saw a clear way forward with sparse sets so just went with that. That's not to say that you couldn't do it with archetypes too but I just didn't see how.
