There is a huge benefit from using Articulate Storyline for online course development. On one hand the course can be used to output both Flash and html5 versions of the same thing including video, interactivity, quizzes and results and on the other hand the program allows quick changes to content allowing revised courses to be available in a matter of minutes.
When we were deciding on the right development platform we looked closely at a few options that ultimately came down to the choice between Adobe Captivate and Articulate Storyline. Both had pros and cons but we feel we made the correct choice with Storyline.
Since using Storyline one of the big pluses has been the support for this product. The forums are great with a good team of supporters and also the support from Articulate has been excellent. When there have been issues that nobody has been able to make sense of we have been able to upload our project and get one of the Storyline experts to have a look at it.
