CreateJS in many ways seems to bring Flash/ActionScript concepts to JavaScript. I used EaselJS and PreloadJS in my Win 8 project, and in a lot of ways it felt like I was back in ActionScript (except for worrying about which page on the timeline - for better or worse).

Agreed. What impresses me most about the CreateJS suite is the ease in which you can use and interact with sprite-sheets. That's the one thing that I feel has been missing from most of the newer open-source drawing / animation libs coming out for HTML5, and really sent me back to the days when I was first learning how to animate in Flash and the joy of seeing it 'simply work' in the browser without much development time.

Easy to use, performant, JSON based, and thus interoperable with many pre-existing tools. I hope it catches on.
