Ha, I am stunned to see there are so many of these!
I’m sure they all work very well, in my own case I’ve been using Deckset for a number of years now and have always been impressed with the polish and usability:
I doubt it uses reveal.js under the hood, but, yeah I think they can effectively do all the same stuff! I just like it because I tried reveal.js (disclaimer, a while ago) and found it kinda fiddly whereas the macOS-native UI of deckset was nicer to use
