If you want to move from Twitter to the fediverse then Mastodon is the closest in terms of how it works. However Friendica allows you to connect with your Twitter and thus cross post automatically on Twitter too, get all of your Friends' posts in your Friendica timeline, reply to them and all that. So it is a proper integration with Twitter.
