I’ve been using Keynote since its release in 2003. It is in my opinion the easiest and best presentation tool overall. It comes included with most Apple devices and is a great option for students and professionals who use an iPad or Mac.

If you are working in a group and need collaboration to be the strength of your presentation, then Google Slides is your solution. This is a popular option for students working on Chromebooks or other computers where they need to be able to work in a group on a presentation project, and for the teachers who instruct them.

This web-based tool is the best option I have found for features and price when you want real-time engagement with your presentation, whether you are teaching a class, presenting online, or want to truly know if your audience is tracking with you or how to customize where you go next based on their feedback in the moment.
