I’m probably totally out of the loop on this. What presentation software is currently widely used? If you were to do an audio-visual presentation in your job, what do you use? Is PowerPoint still widely used or is there something cooler and better? Prezi? Sway? I haven’t used them, but have colleagues who have.
In my field powerpoint still dominates. I can see some advantages of prezi, but I've also seen it used by people who were trying to get in on the new thing but didn't invest the time in learning how to use it effectively. I suggest using whichever one you know best and will enable you to give the most polished presentation.
