PeerTube in general is the best alternative so far. TILvids is an example of a PeerTube instance, but PeerTube is federated just like Lemmy here, so you can find a different instance if you don’t like TILvids, or even host your own if you want! I don’t know the best instance for you off the top of my head though, I just use TILvids as well, which works fine for me as just a viewer.
