I watch a lot of live DJ streams (and have done some myself), and basically right now everyone is either using Twitch or Mixcloud.
Twitch - doesn't enforce any takedowns when you're live, but will mute you after the fact in clips/etc. Very gamer-y, but has friendlier chat features, emojis, and some meta-games around unlocking them. Also has support for hosting (showing someone else's channel in your own for a period of time) and raiding (relocating everyone in your channel to someone else's), which are key for people that want to do multi-artist events.
Mixcloud - smaller, but actually has a licensing deal so muting is far less common. Chat is primitive (no @'s, limited emojis). Streaming quality is good, though.
Facebook - basically a non-starter as they'll mute you live. Only really works if you're playing a literal live show with a band, where you're making noise that the algorithms won't pick. Reach is obviously much bigger, as the platform will shove live videos in your face if people have already liked your fan page.
