Tried Jerboa, Sync and Thunder (and Artemis + web app for kbin).
Sync seems the most polished because it came from Reddit, but the fact that you can't post in Sync right now makes it really hard to dig in and dedicate to it.
Thunder feels like a more polished version of Jerboa, but I'm not a huge fan of the Material You design and big iconography in any of these apps (I came from RIF, so I'm used to basically early 2010s UI, lol).
Artemis is unevalautable right now given its severe alpha state.
And of course, lemmy.world is having connection issues, so none of the apps really "work" right now, no fault of their own. At least Thunder seems to cache old data, since it's populated when I open it, versus Sync which can't make a connection.
Please excuse my maybe stupid question, but did you manage to move your account from lemmy.world to another instance?
If so, would you please share how you did that?
Not stupid, it isn't straight forward, there's a python script that helps with transferring subscriptions, posts and comments can't be transfered though
You can use Lasim to download your profile settings and subscribed communities from Lemmy.world and then upload to your new account.
You need a computer tho, it isn't a mobile app.
