Now that Sync and Infinity are out, which do people prefer? Also, how do they compare to the existing lemmy apps?

Sync is great, but I'm not the biggest fan of introducing ads in a service that doesn't inherently have ads - nothing against the dev getting paid. You also can't currently create a new post (just says "coming soon"). I used Sync on Reddit for years, so I'm otherwise pretty biased toward it.

Connect is a close second, for me. It's still a work in progress, but I feel it's pretty close to Sync. Given time, I think it'll be there. The dev is also very responsive. Features are pretty community driven as well - so if you want something, post in the community.

But I have to say, for its lack of polish, Jerboa still comes out on top for me. It's not as smooth scrolling the feed and it needs an option to handle links in-app, but with it being open source and there being a bunch of contributors adding features, every time I think it's missing something, it's just a matter of waiting for the next update. The one from today added DMing, which was the big thing I saw other apps handling better. Plus, I think (other than Sync), it's the only app that handles multiple accounts the best if you want sorting and defaults per account rather than app-wide.

I also still pop into Thunder, Summit, Liftoff, and Voyager periodically to see how they're coming along. And now, I'm including Infinity (and Boost or any others whenever they're ready).

At the end of the day, people are just going to have to try the different apps for themselves to see what works for them.
