It's funny how Microsoft has an absolute beast on their hand with Powerpoint, which has so many obscure and powerful features that their employees must be fuming at how it's all just there, and nobody uses them. Fractals, high-res fish models, it's Turing complete for Pete's sake. They could easily destroy their competition if only they got somebody in charge to do it.
For instance, the PowerPoint integration with Teams is slick, where you can independently navigate and then join the presenter again (at presenter's option). Or teams actually co-edit remotely while lead is presenting, team members are editing on the fly, and others/guests are viewing the presenter's choice of a native presentation or a window or a screen... not to mention any/all of this working on Surface Hub conference room touch screens.
I used to be a Keynote person, then Deckset, then a couple different markdown slide tools ... but for team based work these integrations have pulled me back into PowerPoint "at the office".
I still hate most of these tools though, slide-ware is where knowledge goes to die.
