Memmy has sort of been the “best” Lemmy app (in terms of features and popularity) but the devs stopped releasing updates and the last update was about two months ago. However, there has been activity recently on their GitHub page so hopefully we’ll see another update soon.

I was hardcore on Memmy but switched to Avelon and have been super happy with it. I will def be checking out Memmy again if an update comes out soon though.

You're right that Jerboa is designed by the Lemmy devs but it's by no means the official app. I've used it for a few months and it's got some issues but they've definitely made some large improvements in reliability over the past 2-3 months. I definitely wouldn't say it's feature rich, but it gets the job done.
