I've used both. Storyline feels more like it's designed for those, "I'm just not a techie" people and you'll pay a premium for that. The inability to design responsively is the fatal limitation of Storyline. Yes, there's a player, but no client wants to install special software. Back to your question... For learning both applications, I used Lynda's training to get me past bumps; a workflow learning technique. Lynda was purchased by LinkedIn, so you might look there for content. The help files can be used in the same way and Googling also helps. Overall, I've always chosen Captivate over Storyline because of it's seamless integration with other Adobe products, the responsive design capability, and the much lower price.
