If the diagrams and descriptions are actually well-designed and written, I'd far prefer those. Especially one where I can ask clarifying questions. I'd much prefer a Haynes with some of the images lightly animated than having a 10 minute long video with a long intro for monetization reasons about how to do some simple thing where you can barely see what the mechanic is actually doing in the cramped, poorly lit, 360p video is trying to look at.

But getting actual service manuals cheap/free these days can be tricky, and their quality can leave a good bit to be desired.
