your prefered opensouce alternative to facebook?

hello

i use a bit mastodon to filter a bit requsets from others people on several ineternet plateforms (reddit, forums..) eg i just let a mastodon instead of email or xmpp

well, i was thinking :

to just share contents between people, by not using facebook (nor mastodon), would you prefer :

friendica?
diaspora?
movim?
hubzilla?
mobilizon?
or others?

in which type of context?

thank you for your feedbacks :)
