Yup, i don’t know much about kbin (it’s both a microblog and a forum, not really my taste) But piefed is great. Only thing i miss is 3rd party UIs :(

I don’t like the UI but the features are awesome, and the developer is active. You can even directly vote for features. There’s also polls and unlike the Lemmy devs he isn’t a PTB so that’s cool too.

Lemmy can be annoyingly slow at implementing features, here’s an example: https://codeberg.org/rimu/pyfedi/issues/181, and https://github.com/LemmyNet/lemmy/issues/787.
