I also manage a site that uses LearnDash and was not impressed or inspired by it.
When I had to rebuild one of my own sites with an LMS solution I went with AccessAlly and have been blown away by their system. So much better than every other LMS solution I’ve worked with or tested out.
AccessAlly’s support gives quick responses to get answers to my questions.
I’ve been setting up some pretty advanced stuff and AccessAlly has been able to do what I want to do every time.
