What exactly did you not like? Using it now and it's come a huge way in just a few weeks. Of all the apps I've tried it had the most compact and quick interface.
I feel people had a lot of loading issues when instances were going down left and right which gave Jerboa an unfair reputation through no fault of its own.
As an ex-RIF user, Jerboa was the one I stuck with, I've just switched to the new Voyager native app, partly because there were some minor feature issues, and performance issues in the last week, mostly just the app crashing when running into comments of blocked users and when scrolling longer threads. They also changed the nesting of comments when you select to view them individually from your post screen, didn't like that.
For some reason I could no longer post replies to comments. I could log in, but it kept me stuck on anonymous for some reason. It also had pretty crap sorting ui so I just ended up seeing the same posts for days at a time, and when clicking on links it insisted on opening them in an external browser.
Compared to RiF it wasn't a smooth UX for me. Sync I can tweak and it looks and feels very nice with no issues so far. I'll probably try other options as things mature, but for now this is definitely "good enough" whereas other options weren't for me.
The only thing I'd change about sync UI wise currently is the indentation of the comment actions. When I tap on a comment to upvote I expect it to be aligned with the comment, instead it's always at full width. I keep bookmarking things by mistake.
I never ended up being able to log in. Even after it said they fixed the issue it kept logging me out. And don't get me started on the UI.
Sync ain't perfect. I keep accidentally collapsing comments because I was used to rif which, unlike sync, doesn't collapse comments after a long press. The fact that that is one of my biggest gripes with the app is a huge improvement over jerboa though
The customization on sync gets me so damn close to what I had with relay that I'm just happy.
I used others, but they were heavily inspired by Apollo and the customization to make them closer to my muscle memory wasn't there. I'm happy to pay a talented developer who can give me my preferred experience.
And I really don't get this raging choosing beggar entitlement to people labor for free
