I'm not a fan of the misskey forks because most of them are very buggy and have very bloated UIs. I tried Iceshrimp and hajkey and both were terribly buggy. Sharkey was okay but still very buggy, biggest issue by far is the fact that follow attempts typically hang for long amounts of time if they even go through at all. Not sure if it's a frontend issue though or an issue with the software itself, I tried Sharkey's Mastodon API to use the Mastodon app and it seems to work okay there. I still wouldn't trust it over mastodon which is much more polished and stable.

There are some cool features in it like the cat ears, the gallery, and very robust theming elements, but ultimately stability and usability come first for social platforms I'm going to use seriously
