Hey, so better is more of an objective term - piefed offers a more comprehensive moderation experience for admins and mods, and addresses some of the issues that users raise around multiple communities and account settings etc.

Piefed runs on activitypub just like lemmy does, so are compatible with eachother - you probably already see piefed users and communities in your lemmy feed.

I wouldn’t say there is an argument either way from a user perspective- I’d encourage people to try both and see what they like.

There are no front ends yet that work with piefed (like tesseract or photon) but they’re being worked on. There’s also only a few apps, but similarly these are being worked on too, so before long you can probably interact with either software through an app.

Lemmy was the first and so is the most popular, and I hope the devs are able to bring some of the moderation features over to lemmy too, as it is quite a limited experience in comparison to many fediverse softwares.

Hope that helps, but tldr try both and see which one you like, they can interact with eachother anyway, I.e. piefed.zip/c/home can be interacted with via lemmy.zip/c/home@piefed.zip
