OurFamilyWizard vs Coparently - which one actually works?

Been using OurFamilyWizard for 6 months and honestly it's clunky. The calendar is confusing and my ex still doesn't log in half the time. Considering switching to Coparently because I've heard better things but don't want to start over if it's not worth it. Has anyone actually gotten their ex to consistently use one of these? What made the difference?
