I'm currently using Liftoff more than the others, but every week I'm seeing huge positive changes being made to all of these. Jerboa is an honorable mention, as I don't think we can log in to that yet.
I like the feel of sync, but the fonts are a little small, and there comments in threads are hard to differentiate compared to the apps above.
Maybe I'm misunderstanding you, but I've never had any trouble logging in with Jerboa. It'd be my favorite app but it has framerate issues on my device, so I'm using Thunder.
I was switching between Voyager, Infinity and Thunder until Sync got released. None of those even come close to the User Experience of Sync. It's not even the bugs, it's the interface and the UX.
Okay, I won’t push you from Sync. But if you have the money to remove its ads, please also consider supporting Lemmy directly or indirectly (Mozilla, among other things, funded the effort to find and patch TootRoot before it became a problem). If you don’t want to just donate, switching to Mozilla VPN will also help.
