Nostr has a better UX than ActivityPub IMO, for the basic reason that you do not need to learn how to self-host a server or depend on an unaccountable admin that might shut down the server at any time. In Nostr, you just create an account and go! The big issue is the lack of content, but that's a social problem, not a UX problem.
