Ask HN: How do you craft your slides?

Hi all,

For technical presentations, what presentation framework do you recommend?

I've been experimenting with the React based Spectacle [1] and vanilla JS Reveal.js [2], both pretty useful for presenting code and embedding stuff like video's and iframes.

However, it has been a while since my last presentation and I'm curious if you would recommend either of these options or something completely different.
