Uhmm.. nice question, but can't answer aince I didn't tried it directly, but I don't see features that are pushing me to try it and leave #nostr.

It looks like an even smaller echo chamber.

What makes #nostr great is the number of devs and people constantly working on it, amd this number increase every day drastically, since normal user are starting to try to participate as much as they can, even starting to study coding.. just amazing, Protocol-Network effect!
