AcademyLMS is a hidden gem.

We use AcademyLMS extensively in combination with StoreEngine, all works seamless. As an SME, it is very important to us that support is available, friendly, and effective when we have a question or problem. Communication is superb. The usability and clean code bring well-thought-out features to the LMS, which today leaves almost nothing to be desired.
It's more a question of what you want to do with it, and if something is missing, then add it to the roadmap and sooner or later the AcademyLMS team will make it happen.

For us: 5 tacos and the clear favorite and a must for an LMS on WordPress.
