Captivate is considered to be a 'rapid' authoring tool, same is not the case for Animate. It is perfectly possible to integrate more complex animations created in Animate and exported as OAM in Captivate. With Javascript you can even exchange between Captivate and the OAM. I wouldn't agree with the sentence that Captivate allows less interactivity than Animate, but that is my personal opinion of course. Captivate allows to create responsive projects, using either Fluid Boxes (similar to Muse) or Breakpoint View work flow. It has roundtripping with Photoshop (for bitmap assets), Illustrator (for SVG's) and Audition. You can use PhoneGap directly from Captivate to publish an app. Captivate allows to create SCORM output (can you with Animate?) to be used in combination with a LMS or an internal server to track users and report scores for assessments. Captivate is moreover the tool to create interactive software training and assessment. As a bonus, you'll get a video capture tool (similar to Camtasia) with an easy way to integrate software video into a interactive course. You should have a look at Captivate and learn some JavaScript to extend its functionality to unknown limits. It is a much underestimated application.
