Camtasia or Articulate?

Quick question for BPMS Watch readers. In my BPMN training I used Camtasia Studio to produce the Flash videos from Powerpoint and screencams. Of course, now I want to change the slide masters, tweak a few slides, the usual thing. But the simplest change in the Powerpoint can mean a huge effort in Camtasia. Changing the slide master? Probably 20 hours to re-record the video and re-sync the audio to the slides. I'm told Articulate is much better, very little effort to accommodate a change in the Powerpoint. Anyone out there have experience with this?
