I'm using photosync with photoprisim and it works fine to autosync photos off, with the only caveat being that i'll occasionally close the app and it won't run for a few days/weeks.
Not as seamless as iCloud Photos but it works great.

I still have to click the notification, due to iOS limitations but having the notification show serves as a good reminder to run it.
