Articulate, let's talk pricing...

The one item missing from your list is the direct-competitor to Storyline, Adobe Captivate, which is priced at $34/month ($408/year).

Dreamweaver (with the old CourseBuilder Extension) was the de facto "low end" authoring tool, Captivate was the mid-range tool, and Authorware, Director, and Flash were the high-end development tools. With the demise of Authorware, Director, and Flash, and developers today not asking for a lot of the functionality those tools offered, Captivate moved to the top of Adobe's eLearning tools as its lone offering of consequence in the eLearning development space. DreamWeaver moved away from being an eLearning development tool years ago.

Note, I am NOT dissing Adobe, as I was a Captivate user from when it was called RoboDemo, Director user since the company was MacroMind, and a few of the testimonials for Captivate are from long-time friends from the Authorware space, but all of that was from when MACROMEDIA sold the tools.
