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
There are a lot of results under this you can see at https://strawpoll.com/wby5A21R1yA, I just took a screenshot on my phone and that's what fit and didn't feel like doing a really long screenshot lol
Liftoff is pretty great though, I used it as my primary for a while and still use it occasionally
