Not an answer to your question, but my experience of browsing lemmy has improved after hiding all scores.

I haven’t used piefed myself but I wouldn’t want to switch to it because I feel like it gives more power to downvotes and karma (or “reputation” as they call it):

• Comments with -10 score are collapsed by default.
• People who get downvoted a lot end up with a ‘low reputation’ indicator next to their name. You’ll know it when you see it.
• Upvotes in meme communities do not add to reputation.

Those are three of the twelve points listed as differences to lemmy on their features page.

I also don’t agree with some of the points in their article on “PieFed features for growing healthy communities”.
