Personally I was a Boost fan and I'm excited for its release for lemmy. But I'm using sync in the meantime and absolutely loving it. There's a smoothness to this app, a refinement if you will that I couldn't find on any of the other apps. The level of customization to make my feed my own.
Totally on point.. Like you, I am a boost user, but the experience here in sync so far is the best regarding all other apps.. Either way, before this, I was using thunder nightly and so far so good.. Now, I'm waiting for boost to decide for which one I'm gonna go as premium user..
I've been jumping between Jerboa, liftoff and now sync. Sync just has a smoothness that the other two apps don't have, at least in my experience on my pixel 6 pro, scrolling and everything is butter smooth on sync, the others have some odd stutters sometimes
