I don't know Miro or Figjam very well, but I would say that:

- You can write a Slipshow presentation in Markdown, which can be more convenient than in those collaborative whiteboards (depending on the person): the source file is plain text. - Slipshow is made for presentations, so it is themed for that: the usual ratio for the screen, blocks such as example/theorem/definition, titles, ... - It is easy in Slipshow to reveal new content/go to a new position by simply pressing the "right arrow" key. - The output from Slipshow is a single file that you can view offline, send to your audience, ...

There might be more differences. For sure, those tools are different and adapted to a purpose, or a style of presenting. For some kind of presentations, Miro and Figjam might be much better than Slipshow!
