I've got Jerboa, Liftoff, and Connect installed and found myself primarily using Jerboa for stability reasons (that said anyone with an account on Lemmy.world is going through it with growing pains regardless of the app).
Jerboa has definitely been my preferred client so far, but if you run into any others that you end up liking please report back here as I'm open to trying any of them.
I really like the look of Liftoff better than I am liking the look of Jerboa, but that just comes down to personal preference. Once thing I don't like about Liftoff is even when I swap accounts it still shows like upvotes and boosts from my main account and I can't do them on my secondary. I might try Connect next, but I am looking forward to trying sync in beta as well.
