Thunder is the only one I've used so far. No complaints at all, I just wish I could, instead of building a large list of subbed communities, just filter out certain communites from my feed. Maybe it's coming, maybe we already can 🤷♂️
Thunder is the best so far IMO. It has so many features, runs smoothly, has a great search function. One of the only things I think it needs more of is theming.
Edit: came back because since this comment I've been using Connect and haven't looked back.
!Lemmyconnect@lemmy.ca if you want to check it out. Amazing app.
I considered Thunder however exodus reports that it contains user tracking anti-features which tracks and reports user activity whereas the other two options avaliable in the F-Droid store: Liftoff and Jerboa are clean and respect user privacy.
