Having used many different tools to create presentations, including sozi, and jessyink (svg to presentation tools using inkscape), Markdown tools (reveal, sli.dev, reveal via org mode) and power point, I actually find that using Markdown tools typically leads to less text in slides (I know this is counterintuitive). You essentially often end up with a single statement/single image type slides that one often sees in "inspirational" type presentation (e.g. Ted talks. There in also lies an issue with Markdown presentations, more complex layouts (e.g. a side by side comparison) often require tweaking css/html and are more inconsistent. Unfortunately I find it very hard to avoid layouts like these for deeply technical content.
