I've heard good things about Sharkey, it's what blahaj uses for their microblog stuff.
There's also Iceshrimp, though last I heard they were becoming their own thing written in C#.
The others I know about don't seem to be maintained. Can't speak to using them, I find the interface far too busy (default Mastodon UI users).
I wouldn't call Bluesky's federation fake, we'd need a working definition of 'federation' for that, but I would say it lacks meaningful federation.
