Misskey forks and Mastodon all have a file drive to manage things, thread watching, one-click access to LibreTranslate without browser extensions (good for libraries and school). Lemmy is really only good for the insane blood bowl of comments sections - and I literally have to use SearxNG lemmy comments plugin to sift through it because federation is so annoying. Though I am being harsh maybe. Eh honestly it's workable if you babysit every aspect of federation but it was never worth it to me. A.gup.pe is pretty much the best way to bridge Lemmy with Mastodon/Misskey/Friendica forks.
Let's be for real though, Mastodon's ecosystem is horrible. They all support mindless aggression against Russia and "Israel's right to exist" where Palestinians used to live side by side even with Zionists. The few people who stand up even for international law, which is based in US oriented institutions, are constantly lambasted, to the point even mild radical liberals like that German "immibis" guy are driven to their own instances.
FediMap shows why. Until server hosting is less concentrated in NATO countries you can expect more heavy handed neoconservative moderation. At least there are cool Brazilians.
Literally just use a Misskey fork, Funkwhale, and Peertube.
Thank you for apologizing for posting Twitch drama at least. Finding out Piker used to host a show with Klein made me guffaw. I did get something out of it
