Technical papers convey technical information more effectively than PowerPoint presentations, period. The only edge PowerPoint has comes from managers refusing to read technical papers, making the PowerPoint literally better than nothing.

I mean, you can dig in your heels on that, but it's the rhetorical equivalent of putting your fingers in your ears.

I attended a former partner's PhD defense. She used PowerPoint during it for graphs and other visuals as she delivered DEEPLY technical information. Presentation software is valuable when giving presentations, period.

You just have to know how to use it properly.
