As a MBin user, I think it depends on what you’re looking for:

• If you want to be able to follow and interact with Mastodon users, and microblogging side of the Fediverse in general I recommend Mbin

• If you only care about groups (communities) and interacting with them I recommend Piefed

I have been using both Mbin (Kbin before it) and Piefed quite a bit, and both are very good.

If you want microblogging capabilities and prefer the UI, Mbin is the way to go. If you want the most robust Reddit-like experience with a bunch of quality of life improvements over Lemmy but only one UI and no apps as of now, PieFed is gold.

I think PieFed is my favourite for the time being, as I like the UI and don’t care about apps.

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.
