I was using both jerboa, liftoff before sync came along. But my problem with both was effectively less dense information. And hard to navigate comments. The more I have to scroll the more I dislike it. Sync is good at packing information densely if you wish to do so. But also good at spacing it out if you like that layout.

Jerboa wouldn't let me save any posts or comments. Other than that it worked great. I'm using sync now as I had the sync for Reddit back in the day and love it.
