Mastodon is on a much, much larger scale and userbase than lemmy. I think its ready for primetime. Im just mad it federated with Threads

…Which one? /s

I tease, but honestly it is important to remember that Mastodon isn’t one site/instance/platform. You can find Mastodon/Misskey~Firefish~Akkoma/other ActivityPub microblogging instances that aren’t federating with Threads.
