I did a poll and nearly 30% of the people who voted said they used Sync! It’s stayed around that percent the whole time too!
EDIT: Here is the poll I forgot to put this here like five times lol https://strawpoll.com/wby5A21R1yA
If you aren’t the kind of person that says things along the lines of Sync is bad because it has an ad supported version which is optional but it shouldn’t be optional for some reason, then we aren’t talking about you.
to answer your question, sync has a nice and modern user interface that is enjoyable to spend your time with.
Jerboa is… functional, Sync has design and thought behind its interactions and user experience. If that’s okay with you, then that’s fine. But I wasn’t happy there.
