Litmos has an excellent user interface. It's well designed and intuitive. It also has a great content engine. I'm one of the admins, so I create content in the system and use that to produce courses. We make our own training content and credit records. They recently added a new feature called the Course Content Creator, and I'm a big fan. I also like that Litmos lets you record online and face-to-face training so you can create what they call Instructor-led Training Events (ILT).
