I rarely need anything more than bullet points or an image in my presentations, so I don't find them limiting. However, most of these allow arbitrary HTML/JS/CSS, so I wouldn't say they're that limiting. I occasionally include iframes, for example.

The big downside for me is you don't have easy pixel-level control over layout like you do in PowerPoint or Google Slides. Even changing font size, for example, is a little clunkier. I hear some people also miss being able to draw diagrams and flowcharts.
