I've used liftoff, connect, Jerboa, voyager, and sync. For me personally, sync is easily the best app functionally out of all of them, followed by voyager. I liked liftoff better than Jerboa, but stopped using it and went mainly to using voyager because of how liftoff handled messaging which I found frustrating and confusing. Idk if they've changed it since then, but that ship has sailed for me anyway since liftoff doesn't offer anything I want that I couldn't get from sync or voyager. I didn't use connect much because it was very buggy for me so I can't really compare it to the others. Voyager is my next choice after sync, but it still had a lot of issues that I haven't experienced with sync so it's still only my second choice.

I'm biased, since I've liked sync since I used it for reddit, but I'm not a stan by any means. I'm waiting to see how things play out since the app has only been available publicly for a day or two. Personally, I think if someone wants to make a salty post in the liftoff community about another app that isn't liftoff, then it's only fair that people who use that other app can share their own opinions in the comment section of a post on a public community, particularly when the post specifically brings up that other app as a topic.
