I was going to bring a similar analogy; the beauty of ActivityPub and these sites are that as long as they implement the standard in a similar way, they simply become different front-ends to view the same data. There isn't a versus as much as which do you prefer? It's going to be one of the great things about the Fediverse going forwards is the ability to create multiple ways of viewing the same data; each one will attract specific users and no longer will content be walled off between them.
