Lemmy is currently more mature and written in rust for safety. But development is very slow and the developer doesn’t seem that concerned. And lemmy as of five months ago still hasn’t put in development for mods to get their job done (https://lemmy.world/post/25339515/14978968)
Piefed is written in python. Devs seem more active and they’ve focused on speeding up popular features that people want from their social media discussion site. I haven’t used piefed yet. I don’t know if piefed actually provides more mod support which would be a big game changer.
The only solid number I know is that somebody a year ago compared their resource use and lemmy was using like 12x the resources of piefed.
Edit: Ada hasn’t noticed any resource issues, see the rest of the thread.
