My preference is text with steps with screenshots. That way I can do the steps one-by-one, and easily go back and see what I was to do.
With a video, I probably wouldn’t do it as it’s too hard to quickly look at what the steps are. At least for me.
A video might be nice to get an overview of the topic, but for actually doing it, the steps with screenshots works best IMO.
Others may prefer video.
