There's this comparison article (written by a Bluesky user) very recently:
https://shreyanjain.net/2024/07/05/nostr-and-atproto.html
Just in case this is useful to you
it is a great article!
in particular I think a lot of the ideas in both nostr and atproto come from SSB and prior systems. atproto was also pretty informed by ActivityPub; I don't think there was much direct atproto/nostr cross-pollination, though there has been interest in the labeling system
strong urge to hop over and check that all the bolts are tight
