Anyone use Matrix, Pixelfed, Mastodon, Funkwhale, Friendica, etc? Recommendations on instances to join?

Like the title! Does anyone use any of these? Considering branching out, right now I only use Lemmy (I have accounts on Lemmy.ml, Lemmygrad.ml, and Hexbear.net that I swap between depending on mood). Lately I have been considering branching out. What are y'alls experiences? Any recommendations for instances?
