It depends on your values and what kind of experience you want. For me, I couldn’t find a piefed instance that met all my criteria.

I wanted no instances blocked, no flagged users for low karma (I didn’t want karma to matter at all,) able to see greentext communities (4chan screenshots are blocked on some, if not all piefed instances,) and be able to see the modlog.

Piefed has additional features that lemmy lacks, like following individual users and multi-coms, but it wasn’t enough to get me to switch.

I like the openness of the lemmyverse, since there’s more room for individuality between the instances without a developer ideologically holding the reins, though I’ve heard Rimu has walked back their more controversial decisions. For all the criticisms of ML and Grad, the developers affiliations don’t pollute the wider fediverse.

Whichever you choose, make sure you look into the instances as well, since they have unique features, blocklists, and supports for apps.
