Generally speaking I think a lot of the nostr bots are cool but I also have most of them blocked personally.
Collectively they are a bit too spammy for me, especially the ones that post some generic information (news, price quotes, games) every few minutes. If you want to have a global feed outside of your immediate followers you are bound to run in to several.
I think the conversational (chatgpt) types are much more interesting, but the post volume is extreme and much harder to avoid.
