I really like reveal.js, you can use all the modern web technologies in your slides and it provides you with all you need (including speaker notes).
Even if your presentation runs offline the browser is really good place for presentations to live at. E.g. I can include live circuit simulations on slides using circuit.js and if a student asks whst would happen to the output of a signal processing circuit if there was one more component I can just add it. If a question shows up that isn't in there I press ctrl + t and search for an image or a wikipedia article on the topic.
The only thing one has to think about is maybe to create a "clean" browser profile for presentations so your suggestions and personal things don't show up mid presentation.
