Never used Sync for Reddit, and it’s cool that Lemmy is getting a lot of choice in apps. The app seems quite nice, but a paid, closed source model is off-putting for me (including tracking on the ad supported version). Also, I feel like Voyager is a better experience overall, and does a better job of handling the Lemmy/fediverse specific features. I’m sure that will improve on Sync over time of course, and if people prefer it then great!
