It’s basically forum discussion vs microblogging, and they are different types of social media. I myself prefer a forum type format because the focus of discussion is on a topic and doesn’t need my identity to be involved in. It’s also hard to maintain a conversation on a microblogging format when many people are replying to each other at the same time, unlike a forum where there are nested threads. It’s the reason I never got into twitter.
I did try mastodon because it was on the fediverse, but stopped posting after 2 weeks because I couldn’t think of anything interesting to post and it was hard to follow conversations with other people. It was also weird knowing there were people "following" me and will see everything I post.
