Can anyone suggest a good high level comparison of ATProto with other decentralised social software protocols like ActivityPub, Matrix or Nostr?

One that's technically accurate, without getting too deep into the weeds. One that confirms or debunk's BlueSky's claim that the only thing required to make BlueSky meaningfully decentralised is more vendors participating. Either by hosting PDS, relay and appview services, and/or writing independent ATProto implementations.
