I like that it has a lot of customization options for different types of learners. It's also very easy to get started with. The interface can be a little confusing at first, but once you figure out how to use it, it's great! We've been able to create a number of different courses and we're finding them very useful. I'm not sure that any one thing in particular stands out as being particularly good or bad; there are just some things that could probably be improved. I would say that the support is excellent. They are always quick to respond to questions and they really do care about helping customers succeed. There aren't many things that I dislike about Persona. I did have an issue with the customer service team at one point. But they were extremely helpful and resolved my problem quickly.
