Tbh, none of them really attract me right now. They are too clunky and don't have many people to interact with. I'm slightly annoyed by Nostr's proposition and total lack of moderation controls. Even if its developers are well-meaning, I see this as a dangerous, undesirable position to take.
I'm really comfortable with Mastodon/ActivityPub. My personal profile is in a public instance[0], and for my Portuguese-written site I'm hosting a Microblog[1]. It's just great.
