I started using Storyline less than a year ago.
I got the trial version of Studio (Presenter, Engage and Quizzmaker) and Storyline, and I tested both.
Presenter is very easy to use, because it works with PowerPoint. You create the slides, record the narration and synch the animations. Some Powerpoint animations do not work in Presenter. I tested Engage and Quizzmaker too, and these are interesting tools. But you have to move from a program to the other, and this really bored me.
I chose Storyline because I have to record software simulation, and it has the html5 option. I think I made an excelent choice. It's not as intuitive as Presenter, but when you open the program it shows some links to tutorials: "Getting started", "Inserting content" etc, and I progressed step by step.
I subscribed to the Articulate community blogs and they are my post-graduation course. I love the Weekly Recap of the "Word of Mouth" blog, and Tom's blog is fantastic, I've spent hours and hours reading his posts.
My firsts tutorials were " "death" by power point online", as you've said, but they have been improving as I learn new features. In the begining they were very simple, and now I can create some more complex things.
